Question : A man sells a good at 5% profit. If he had sold it at a 10% profit, he would have received INR 175 more. What is the selling price of the good?
Option 1: INR 3,750
Option 2: INR 3,850
Option 3: INR 3,675
Option 4: INR 3,500
Correct Answer: INR 3,675
Solution : Let the cost price be Rs. $x$. As per the given conditions, $\frac{105x}{100}+175=\frac{110x}{100}$ ⇒ $\frac{5x}{100}=175$ $\therefore x=3500$ Now, selling price = $\frac{105x}{100} = 3500\times \frac{105}{100}=3675$ Hence, the correct answer is INR 3,675.

Question : Simplify the following expression. $\{[(x-5)(x-1)]-[(9 x-5)(9x-1)]\} \div 16x$
Option 1: $2x(5x-3)$
Option 2: $-(5x-3)$
Option 3: $x(5x-3)$
Option 4: $-6x(5x-3)$
Correct Answer: $-(5x-3)$
Solution : Given: $\{[(x-5)(x-1)]-[(9 x-5)(9x-1)]\} \div 16x$ $= [(x^{2}-x-5x+5)-[(81x^{2}-9x-45x+5)]\div 16x$ $= [(x^{2}-6x+5)-[(81x^{2}-54x+5)]\div 16x$ $= [(x^{2}-6x+5-81x^{2}+54x-5)]\div 16x$ $= [-80x^{2}+48x]\div 16x$ $=[-5x+3]$ $=-(5x-3)$ Hence, the correct answer is $-(5x-3)$.

Question : Directions: In the following number pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the option in which the numbers are related in the same way as the numbers of the following pairs. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 9, 56 17,104
Option 1: 11, 83
Option 2: 8, 51
Option 3: 12, 69
Option 4: 15, 92

Solution : Given: 9, 56 17,104
Here, multiply the first number by 6 and then add 2 to the resultant to get the second number – ⇒ 9, 56→9 × 6 + 2 = 56 ⇒ 17,104→17 × 6 + 2 = 104
Let's check each
Question : If $P:Q=1: 3, Q:R=3:4,$ and $R: S=2:1$, then what is the value of $P:S$?
Option 1: $3:1$
Option 2: $2:1$
Option 3: $1:2$
Option 4: $3:2$
Correct Answer: $1:2$
Solution : $P: Q = 1 : 3, Q: R = 3: 4, R: S = 2 : 1$ So, $P:Q: R=1:3:4$ Now, $R:S=2:1⇒R:S=4:2$ So, $P:Q:R: S=1:3:4:2$ $\therefore P : S = 1 : 2$ Hence, the correct answer is $1 : 2$.
