This is a coding-decoding problem where letters are assigned specific numerical codes. We need to identify the code for each letter by comparing the given coded words and then apply those codes to find the code for "JUNE".
Let's look for common letters across the given words to deduce their codes.
Now, let's re-examine JINX (5862). We need to find the codes for J, I, N, X. Since no other word shares these letters (except potentially U, which is not in JINX), we need to assume a direct mapping based on position.
Let's list all letters and their codes we have found or can deduce by direct mapping:
Notice that 'U' is 3 in ZEBU and 3 in FUZE. 'Z' is 4 in ZEBU and 4 in FUZE. 'E' is 1 in ZEBU and 1 in FUZE. This confirms a consistent letter-to-digit mapping.
So, the individual codes are:
Using the codes identified:
Therefore, JUNE = 5361. Wait, let's recheck the options and my deduction. There might be a slight error in my manual deduction or the problem's intended mapping.
Let's re-evaluate the common letters and their positions carefully:
Comparing ZEBU and FUZE:
Let's list the mappings directly from the given words:
Let's use a table for clarity:
Letter | Code (from JINX) | Code (from ZEBU) | Code (from FUZE) -------|------------------|------------------|------------------ J | 5 | | I | 8 | | N | 6 | | X | 2 | | Z | | 4 | 4 E | | 3 | 1 B | | 7 | U | | 1 | 3 F | | | 9
There's an inconsistency in my previous deduction or the problem's mapping. Let's re-examine the common letters and their codes from the given examples:
Common letters: Z, E, U. Common digits: 4, 3, 1.
This is a consistent mapping for Z, E, U. Let's update our table:
Letter | Code (from JINX) | Code (from ZEBU) | Code (from FUZE) -------|------------------|------------------|------------------ J | 5 | | I | 8 | | N | 6 | | X | 2 | | Z | | 4 | 4 (Consistent) E | | 3 | 3 (Consistent) B | | 7 | U | | 1 | 1 (Consistent) F | | | 9
So, we have:
Now, let's find the code for JUNE:
So, JUNE = 5163.
C) 5163 — Based on the consistent letter-to-digit mapping derived from the given coded words, the code for JUNE is 5163.
The given pie chart shows the total sales by different mobile companies in the year 2017.

The question asks for the sales made by Vivo company based on a pie chart showing the percentage distribution of total sales among different mobile companies in 2017. The total sales amount is given as 5000 crores.
Correct Option: A) 300
To find the number of three-digit numbers divisible by 8, we first need to identify the smallest and largest three-digit numbers. Then, we find the first three-digit number divisible by 8 and the last three-digit number divisible by 8. Finally, we use the formula for the number of terms in an arithmetic progression.
The smallest three-digit number is 100.
The largest three-digit number is 999.
Divide 100 by 8:
\[ 100 \div 8 = 12 \text{ with a remainder of } 4 \]This means \(8 \times 12 = 96\) (which is a two-digit number). To find the next multiple of 8, we add 8 to 96, or subtract the remainder from 8 and add it to 100.
The first three-digit number divisible by 8 is \(100 + (8 - 4) = 104\).
Divide 999 by 8:
\[ 999 \div 8 = 124 \text{ with a remainder of } 7 \]This means \(8 \times 124 = 992\). To find the largest three-digit number divisible by 8, we subtract the remainder from 999.
The last three-digit number divisible by 8 is \(999 - 7 = 992\).
We have an arithmetic progression where the first term \(a = 104\), the last term \(l = 992\), and the common difference \(d = 8\). The formula for the number of terms \(n\) is:
\[ n = \frac{l - a}{d} + 1 \]Substitute the values:
\[ n = \frac{992 - 104}{8} + 1 \] \[ n = \frac{888}{8} + 1 \] \[ n = 111 + 1 \] \[ n = 112 \]Thus, there are 112 three-digit numbers divisible by 8.
Correct Option: D) 112
What will be the momentum of a body of mass 50 kg moving with a velocity of 20 ms–1?
To find the momentum of a body, we use the fundamental formula that relates mass and velocity. Momentum is a vector quantity, but in this problem, we are only concerned with its magnitude.
Momentum (\(p\)) is defined as the product of mass (\(m\)) and velocity (\(v\)).
\[ p = m \times v \]The standard unit for momentum is kilogram meter per second (kg m/s) or Newton-second (N s).
Correct Option: D) 1000 kg ms–1
The momentum of the body is 1000 kg m/s, which matches option D.
The question asks to identify the correct properties of isotopes of an element. We need to recall the definition of isotopes and their characteristics regarding atomic mass, atomic number, and chemical and physical properties.
Correct Option: B) (ii), (iii) and (iv) are the correct properties of isotopes. Isotopes have the same atomic number, exhibit different physical properties, and exhibit similar chemical properties.
To find the mass of acid in the mixture, we first need to determine the total number of parts in the ratio. Then, we can calculate the mass corresponding to one part and multiply it by the ratio part for acid.
Identify the given ratio: The ratio of salt to acid is \(5 : 7\).
Calculate the total number of parts: Add the ratio parts for salt and acid.
\[ \text{Total parts} = \text{Parts of salt} + \text{Parts of acid} = 5 + 7 = 12 \]Identify the total weight of the mixture: The total weight of the mixture is \(360 \text{ g}\).
Calculate the weight of one part: Divide the total weight of the mixture by the total number of parts.
\[ \text{Weight of one part} = \frac{\text{Total weight of mixture}}{\text{Total parts}} = \frac{360 \text{ g}}{12} = 30 \text{ g} \]Calculate the mass of acid: Multiply the weight of one part by the ratio part for acid.
\[ \text{Mass of acid} = \text{Weight of one part} \times \text{Parts of acid} = 30 \text{ g/part} \times 7 \text{ parts} = 210 \text{ g} \]D) 210 gm is the correct answer. This is calculated by finding the total parts in the ratio (5+7=12), then determining the weight per part (360g / 12 = 30g/part), and finally multiplying the weight per part by the acid's ratio part (30g/part * 7 = 210g).
To calculate the fire insurance premium, we first need to determine the total value of the house and household articles. Then, we calculate 80% of this total value, as the insurance is taken for this amount. Finally, we apply the given premium rate of 7.5% to this insured amount.
The insurance is for 80% of the total value.
\[ \text{Insured Amount} = 80\% \text{ of Total Value} \] \[ \text{Insured Amount} = \frac{80}{100} \times 55,000 \] \[ \text{Insured Amount} = 0.80 \times 55,000 = \text{Rs. } 44,000 \]The rate of premium is 7.5% of the insured amount.
\[ \text{Premium} = 7.5\% \text{ of Insured Amount} \] \[ \text{Premium} = \frac{7.5}{100} \times 44,000 \] \[ \text{Premium} = 0.075 \times 44,000 = \text{Rs. } 3,300 \]Correct Option: C) Rs. 3,300
The question asks to identify which of the given cities is located on the banks of the Sabarmati River. This requires knowledge of the geographical locations of major cities in Gujarat relative to its rivers.
Correct Option: D) Ahmedabad is a major city in Gujarat and is well-known for being situated on the banks of the Sabarmati River. The Sabarmati Ashram, a significant historical site associated with Mahatma Gandhi, is also located on its banks in Ahmedabad.
Find the value of 3\( \frac{5}{8} \) + \( \frac{6}{16} \) - \( \frac{5}{24} \) + 3\( \frac{1}{2} \)
\( \frac{751}{24} \)
\( \frac{715}{24} \)
\( \frac{175}{24} \)
\( \frac{157}{24} \)
To solve this problem, we need to perform addition and subtraction of mixed fractions and proper fractions. The key steps involve converting mixed fractions to improper fractions, finding a common denominator (LCM) for all fractions, performing the arithmetic operations, and then simplifying the result.
C) \( \frac{175}{24} \) is the simplified result after performing all the operations.
The question asks about the composition of the mixture used in the froth flotation method for ore concentration. This method is primarily used for sulphide ores and relies on the differential wettability of ore particles and gangue (impurities).
Correct Option: B) Water and Pine oil
This mixture is fundamental to the froth flotation process. Water forms the slurry, and pine oil acts as both a collector (making ore particles hydrophobic) and a frothing agent (stabilizing the froth that carries the ore particles).
