Question : A is 40% more efficient than B. How much time will they take to work together to complete a job which A alone could have done in 31 days?
Option 1: $\frac{217}{12}\ \text{days}$
Option 2: $\frac{515}{32}\ \text{days}$
Option 3: $\frac{215}{12}\ \text{days}$
Option 4: $\frac{517}{32}\ \text{days}$
Correct Answer: $\frac{217}{12}\ \text{days}$
Solution : Given: A is 40% more efficient than B. The time taken by A to complete the task alone is 31 days. Work = Time × Efficiency. Let B's efficiency be 100. Then, $\frac{A}{B} = \frac{140}{100}$ ⇒ $\frac{A}{B} = \frac{7}{5}$ The total work is done
Question : A man purchased some oranges at the rate of 3 for Rs. 40 and the same quantity at 5 for Rs. 60. If he sells all the oranges at the rate of 3 for Rs. 50, find his gain or loss percentage (to the nearest integer).
Option 1: 32% profit
Option 2: 31% loss
Option 3: 34% loss
Option 4: 31% profit
Correct Answer: 32% profit
Solution : Let the man purchase 15 oranges of each type (least common multiple of 3 and 5). The cost price of the first type = $\frac{40}{3}×15=200$ The cost price of the second type = $\frac{60}{5}×15=180$ The total cost price = 200 + 180 = 380

Question : A sum of Rs. 15525 is divided among Sunil, Anil, and Jamil such that if Rs. 22, Rs. 35, and Rs. 48 are diminished from their shares, respectively, their remaining sums shall be in the ratio 7 : 10 : 13. What would have been the ratio of their sums if Rs. 16, Rs. 77, and Rs. 37, respectively, were added to their original shares?
Option 1: 9 : 13 : 17
Option 2: 18 : 26 : 35
Option 3: 36 : 52 : 67
Option 4: None of these
Correct Answer: 36 : 52 : 67
Solution : Total sum = Rs.15525 Distributed sum = 15525 – 22 – 35 – 48 = Rs.15420 The ratio of remaining share = 7 : 10 : 13 New share of Sunil = ($\frac{7}{7+10+13}$ × 15420) + 22 + 16 = ($\frac{7}{30}$
Question : If $P=2^2+6^2+10^2+14^2+....+ 94^2$ and $Q=1^2+5^2+9^2+...+81^2$, then what is the value of $P - Q$?
Option 1: 24645
Option 2: 26075
Option 3: 29317
Option 4: 31515
Correct Answer: 26075
Solution : Given: $P=2^2+6^2+10^2+14^2+....+94^2$ and $Q=1^2+5^2+9^2+...+81^2$ $⇒P-Q = (2^{2}-1^{2})+(6^{2}-5^{2})+(10^{2}-9^{2})+....+(82^{2}-81^{2})+86^{2}+90^{2}+94^{2}$ $⇒P-Q=3+11+19+27+.......+163(\text{A.P. with 21 terms})+86^{2}+90^{2}+94^{2}$ $⇒P-Q=\frac{21}{2}[2×3+(21–1)8]+86^{2}+90^{2}+94^{2}$ $⇒P-Q=\frac{21}{2}[6+(20)8]+86^{2}+90^{2}+94^{2}$ $⇒P-Q=\frac{21}{2}[166]+(90-4)^{2}+90^{2}+(90+4)^{2}$ $⇒P-Q=1743+(90^{2}-2×90×4+4^{2})+90^{2}+(90^{2}+4^{2}+2×90×4)$ $⇒P-Q=1743+8100+16+8100+8100+16$ $\therefore P-Q=26075$ Hence, the correct answer is 26075.
Question : Suman paid INR 9,600 in interest on a loan she obtained 5 years ago with a simple interest rate of 16%. What was the amount of the loan she had taken?
Option 1: INR 13,250
Option 2: INR 12,500
Option 3: INR 12,000
Option 4: INR 11,750
Correct Answer: INR 12,000
Solution : Let the principal be $\text{x}$. We know, Simple interest = $\frac{\text{Principal × Rate × Time}}{100}$ ⇒ $9600=\frac{\text{x × 16 × 5}}{100}$ ⇒ $\text{x}=\frac{\text{9600 × 100}}{\text{16 × 5}}$ ⇒ $\text{x}=12000$ Hence, the correct answer is INR 12000.
Question : The mean proportional of $(a+b)(a-b)^3,(a+b)^3(a-b)$ is:
Option 1: $(a+b)^2(a–b)^2$
Option 2: $(a+b)^2(a–b)$
Option 3: $(a+b)(a–b)^2$
Option 4: $a^2-b^2$
Correct Answer: $(a+b)^2(a–b)^2$
Solution : Let the mean proportion of $(a+b)(a-b)^3,(a+b)^3(a-b)$ be $x$. Mean proportion of $A$ and $B$ = $\sqrt{A×B}$ ⇒ $x=\sqrt{ (a+b)(a-b)^3 \times (a+b)^3(a-b)}$ ⇒ $x = \sqrt{(a+b)^4 (a-b)^4}$ ⇒ $x = (a+b)^2(a-b)^2$ Hence, the correct answer is $(a+b)^2(a-b)^2$.
