To solve this problem, we need to apply the given rules to each digit of the original number. First, identify whether each digit is odd or even. Then, perform the specified operation (subtract 2 from odd digits, add 1 to even digits). Finally, examine the new number formed and count how many digits appear more than once.
C) Two. The digits 3 and 7 occur more than once in the new number 91333577.
Study the given letter-symbol series and answer the question that follows:
L @ S * E ^ B U # W I < E M @ O S # B * H ! A & L < O
If we replace each of the vowels with any consonant and similarly if we replace each of the consonants in the original series with any vowel, then how many vowels will be immediately followed by a symbol in the resultant series thus formed?
The question asks to identify the FALSE statement among the given options regarding cellular respiration and fermentation. We need to evaluate each statement based on biological facts about these processes.
Correct Option: C) In the mitochondria, acetic acid is broken down utilizing oxygen.
This statement is false. In aerobic respiration, pyruvic acid (produced from glucose during glycolysis) is converted to acetyl-CoA, which then enters the mitochondria. Inside the mitochondria, acetyl-CoA is completely oxidized in the Krebs cycle and electron transport chain, utilizing oxygen. Acetic acid is not the direct substrate broken down in the mitochondria in this context. Acetic acid can be formed during some fermentation processes or as an intermediate in other metabolic pathways, but it's not the primary molecule that enters the Krebs cycle for aerobic breakdown in the mitochondria in the way suggested.
The resistance of a wire depends on its material, length, and cross-sectional area. We will use the formula for resistance to establish a relationship between the resistances and cross-sectional areas of the two wires, given that they are made of the same material and have the same length.
The formula for the resistance (\(R\)) of a wire is given by:
\[ R = \rho \frac{L}{A} \]where:
For wire A, the resistance is \(R_A\), length is \(L_A\), and cross-sectional area is \(A_A\). So,
\[ R_A = \rho \frac{L_A}{A_A} \]For wire B, the resistance is \(R_B\), length is \(L_B\), and cross-sectional area is \(A_B\). So,
\[ R_B = \rho \frac{L_B}{A_B} \]We are given that the wires are made of the same material, so their resistivities are equal (\(\rho_A = \rho_B = \rho\)).
We are also given that they have the same length, so \(L_A = L_B = L\).
Substitute these conditions into the resistance formulas:
\[ R_A = \rho \frac{L}{A_A} \quad \text{(Equation 1)} \]\[ R_B = \rho \frac{L}{A_B} \quad \text{(Equation 2)} \]We are given that the resistance of wire A is 16 times the resistance of wire B, i.e., \(R_A = 16 R_B\).
Now, substitute Equation 1 and Equation 2 into the given relationship:
\[ \rho \frac{L}{A_A} = 16 \left( \rho \frac{L}{A_B} \right) \]Cancel out the common terms (\(\rho\) and \(L\)) from both sides:
\[ \frac{1}{A_A} = \frac{16}{A_B} \]Rearrange the equation to find the ratio of the cross-sectional area of wire A to that of wire B (\(A_A : A_B\)):
\[ A_B = 16 A_A \]\[ \frac{A_A}{A_B} = \frac{1}{16} \]Thus, the ratio of the cross-sectional area of wire A to that of wire B is 1 : 16.
Correct Option: D) 1 : 16
X and Y can complete a piece of work in 8 days and 12 days, respectively. If they work on alternate days, with X working on the first day, how long will it take the duo to complete the work?
9\( \frac{1}{3} \) days
9\( \frac{2}{3} \) days
9\( \frac{3}{5} \) days
9 \( \frac{1}{2} \) days
This problem involves calculating the time taken to complete a work when two individuals work on alternate days. We will first find the individual work rates, then calculate the work done in a 2-day cycle, and finally determine the total time.
X can complete the work in 8 days. So, X's 1-day work is:
\[ \text{X's 1-day work} = \frac{1}{8} \text{ of the total work} \]Y can complete the work in 12 days. So, Y's 1-day work is:
\[ \text{Y's 1-day work} = \frac{1}{12} \text{ of the total work} \]Since they work on alternate days with X working on the first day:
Day 1: X works
Day 2: Y works
Work done in 2 days (1 cycle) = X's 1-day work + Y's 1-day work
\[ \text{Work in 2 days} = \frac{1}{8} + \frac{1}{12} \]To add these fractions, find a common denominator, which is 24:
\[ \text{Work in 2 days} = \frac{3}{24} + \frac{2}{24} = \frac{5}{24} \text{ of the total work} \]Let \(N\) be the number of 2-day cycles. We want to find \(N\) such that the work done is close to, but not exceeding, the total work (which is 1).
Work done after \(N\) cycles = \(N \times \frac{5}{24}\)
We need to find the largest integer \(N\) such that \(N \times \frac{5}{24} < 1\). If \(N=4\), work done is \[4 \times \frac{5}{24} = \frac{20}{24} = \frac{5}{6}\]. This is less than 1.
If \(N=5\), work done is \[5 \times \frac{5}{24} = \frac{25}{24}\], which is greater than 1. So, we take \(N=4\).
Work completed in \(4 \times 2 = 8\) days = \(\frac{20}{24}\) of the total work.
Remaining work = Total work - Work completed
\[ \text{Remaining work} = 1 - \frac{20}{24} = \frac{24 - 20}{24} = \frac{4}{24} = \frac{1}{6} \text{ of the total work} \]After 8 days, it's X's turn to work (since X started and 8 is an even number of days, meaning Y just finished). X's 1-day work is \(\frac{1}{8}\).
Time taken by X to complete the remaining \(\frac{1}{6}\) work:
\[ \text{Time} = \frac{\text{Remaining work}}{\text{X's 1-day work}} = \frac{1/6}{1/8} = \frac{1}{6} \times 8 = \frac{8}{6} = \frac{4}{3} \text{ days} \]However, X only works for a full day if the remaining work is \(\frac{1}{8}\) or more. Here, \(\frac{1}{6}\) is more than \(\frac{1}{8}\). So X will work for one full day on the 9th day.
Work done by X on the 9th day = \(\frac{1}{8}\).
Work remaining after 9 days = \[\frac{1}{6} - \frac{1}{8} = \frac{4-3}{24} = \frac{1}{24}\].
Now it's Y's turn on the 10th day. Y's 1-day work is \(\frac{1}{12}\).
Time taken by Y to complete the remaining \(\frac{1}{24}\) work:
\[ \text{Time} = \frac{\text{Remaining work}}{\text{Y's 1-day work}} = \frac{1/24}{1/12} = \frac{1}{24} \times 12 = \frac{1}{2} \text{ day} \]Total time = 8 days (from 4 cycles) + 1 day (X's work) + \(\frac{1}{2}\) day (Y's work)
\[ \text{Total time} = 8 + 1 + \frac{1}{2} = 9\frac{1}{2} \text{ days} \]D) 9\( \frac{1}{2} \) days
The problem presents two letter-cluster pairs and asks us to identify the underlying logic. Once the logic is determined, we need to find an option that follows the same rule. The given pairs are TORPEDO : DEOOPRT and FLICKER : CEFIKLR. By observing the letters in the original word and the transformed cluster, it appears to be an arrangement of the same letters.
A) PERTAIN : AEINPRT
This question tests our understanding of inequalities and equalities. We need to analyze the given statement and determine which of the conclusions logically follows from it.
The statement is: T > G F = B = Z
This can be broken down into two parts:
T > G (T is greater than G)F = B = Z (F is equal to B, and B is equal to Z, which implies F is equal to Z)Conclusion I states: F = Z
From the statement F = B = Z, it is directly evident that F is equal to Z.
Therefore, Conclusion I is true.
Conclusion II states: E = B
The variable 'E' is not present anywhere in the given statement T > G F = B = Z. Since there is no information provided about 'E' in relation to 'B' or any other variable, we cannot establish a relationship between E and B.
Therefore, Conclusion II cannot be determined as true or false based on the given statement.
Conclusion I is true.
Conclusion II is false (or cannot be determined as true).
Thus, only Conclusion I is true.
Correct Option: D) Only conclusion I is true
We need to find the amount spent on repairs. We are given the profit amount and the profit percentage, along with the percentage of cost spent on repairs. We can use these to find the total cost price and then calculate the repair cost.
Profit percentage is calculated on the total cost price (CP).
\[ \text{Profit Percentage} = \frac{\text{Profit}}{\text{CP}} \times 100 \]Substitute the given values:
\[ 20 = \frac{2200}{1.10C} \times 100 \]So, the original cost of the scooter was Rs 10,000.
Amount spent on repairs = 10% of \(C\)
\[ \text{Repairs} = 0.10 \times 10000 \] \[ \text{Repairs} = 1000 \]Therefore, Venkat spent Rs 1,000 on repairs.
Correct Option: B) Rs 1,000
The problem involves finding Keerthi's future age based on a given ratio of present ages and Shanthi's future age. We will use the information about Shanthi's age after 5 years to find her present age, then use the ratio to find Keerthi's present age, and finally calculate Keerthi's age after 5 years.
We are given that Shanthi's age will be 40 years after 5 years.
\[ \text{Shanthi's present age} = \text{Shanthi's age after 5 years} - 5 \text{ years} \]\[ \text{Shanthi's present age} = 40 - 5 = 35 \text{ years} \]The present ages of Shanthi and Keerthi are in the ratio of 7:3. Let Shanthi's present age be \(7x\) and Keerthi's present age be \(3x\).
\[ 7x = 35 \]\[ x = \frac{35}{7} \]\[ x = 5 \]Therefore, Keerthi's present age is:\[ \text{Keerthi's present age} = 3x = 3 \times 5 = 15 \text{ years} \]To find Keerthi's age after 5 years, add 5 to her present age.
\[ \text{Keerthi's age after 5 years} = \text{Keerthi's present age} + 5 \text{ years} \]\[ \text{Keerthi's age after 5 years} = 15 + 5 = 20 \text{ years} \]A) 20 years – As calculated, Keerthi will be 20 years old after 5 years.
