To solve this problem, we first need to determine the cost price (CP) of the computer. We are given the selling price (SP) and the percentage loss. Once we have the cost price, we can calculate the new selling price required to achieve a 7% gain.
Calculate the Cost Price (CP):
Given:
The formula relating SP, CP, and Loss% is:
\[ \text{SP} = \text{CP} \times \left(1 - \frac{\text{Loss\%}}{100}\right) \]Substitute the given values:
\[ 30,875 = \text{CP} \times \left(1 - \frac{5}{100}\right) \] \[ 30,875 = \text{CP} \times \left(1 - 0.05\right) \] \[ 30,875 = \text{CP} \times 0.95 \]Now, solve for CP:
\[ \text{CP} = \frac{30,875}{0.95} \] \[ \text{CP} = 32,500 \]So, the cost price of the computer is Rs 32,500.
Calculate the new Selling Price for a 7% Gain:
We want to achieve a gain of 7% on the cost price.
The formula for the new Selling Price (\(\text{New SP}\)) with a gain is:
\[ \text{New SP} = \text{CP} \times \left(1 + \frac{\text{Gain\%}}{100}\right) \]Substitute the values:
\[ \text{New SP} = 32,500 \times \left(1 + \frac{7}{100}\right) \] \[ \text{New SP} = 32,500 \times \left(1 + 0.07\right) \] \[ \text{New SP} = 32,500 \times 1.07 \] \[ \text{New SP} = 34,775 \]Therefore, the shopkeeper should sell the computer for Rs 34,775 to gain 7%.
Correct Option: A) 34,775
To arrange organic compounds in increasing order of their boiling point, we need to consider the types and strengths of intermolecular forces present in each compound. Stronger intermolecular forces lead to higher boiling points because more energy is required to overcome these forces and convert the liquid into a gas.
The main intermolecular forces are:
We will analyze each compound based on these forces and their molecular weights.
The general order of increasing intermolecular forces is LDFs < Dipole-dipole < Hydrogen bonding < Dimeric Hydrogen bonding (as in carboxylic acids).
Therefore, the increasing order of boiling points is:
\(\text{CH}_4 < \text{CHCl}_3 < \text{CH}_3\text{CH}_2\text{OH} < \text{CH}_3\text{COOH}\)
D) CH₄ < CHCl₃ < CH₃CH₂OH < CH₃COOH
This order correctly reflects the increasing strength of intermolecular forces: CH₄ (LDFs) < CHCl₃ (Dipole-dipole, LDFs) < CH₃CH₂OH (Hydrogen bonding) < CH₃COOH (Strong dimeric hydrogen bonding).
The question asks for the specific term used to describe non-financial benefits provided by employers to employees. This is a common concept in human resources and economics.
B) Fringe benefits — This term precisely refers to various non-wage benefits provided to employees in addition to their normal wages or salaries. Examples include health insurance, paid time off, retirement plans, company cars, housing allowances, and other perks that enhance an employee's overall compensation package without being direct monetary payments.
The question asks for the specific term used to describe the first menstrual flow that occurs at puberty. This is a direct recall question from human biology, specifically reproductive health.
C) menarche
Menarche is the medical term for the first menstrual period in a female. It marks the onset of puberty and the beginning of a woman's reproductive years.
To find the approximate value, we will first round off each number to the nearest whole number. Then, we will perform the operations (multiplication, addition, and subtraction) following the order of operations (BODMAS/PEMDAS).
B) 50 — The calculation using approximate values \(7 - 21 + 16 \times 4\) yields 50, which matches this option.
The question asks for the primary reason why contraceptive methods are used. We need to identify the core purpose of contraception among the given options.
Correct Option: B) To avoid pregnancy
Contraceptive methods are specifically designed and used to prevent conception, thereby avoiding pregnancy. This is their fundamental and primary purpose.
The modern periodic table is arranged based on the electronic configuration of elements. The number of valence electrons (electrons in the outermost shell) directly corresponds to the group number for main group elements (groups 1, 2, and 13-18). For groups 13-18, the group number is 10 plus the number of valence electrons.
Correct Option: C) 17ᵗʰ group
The question asks to identify the conditions under which a substance is said to be reduced in a redox reaction. Reduction is one half of a redox (reduction-oxidation) reaction, where one species gains electrons and another loses them. We need to recall the various definitions of reduction.
Correct Option: A) A substance is said to be reduced if it gains hydrogen or loses oxygen. Both of these are classical definitions of reduction, which are consistent with the modern definition of gaining electrons.
The given pie chart shows the sales of a store in each quarter as a percentage of total sales. Study this pie chart and answer the question that follows.
Which quarters have the highest and lowest sales, respectively?
To determine which quarters have the highest and lowest sales, we need to analyze the percentages given in the pie chart.
Correct Option: D) 2 nd and 3 rd
