B. 18% less
C. 8% less
D. 13% less
E. 22% more
Answer: Option D
Explanation:
Expenditure of A in 2011 = [latex] \frac{510} {1.2}[/latex]= 425 lakh
∴ Required percentage = [latex] \frac{490 - 425} {420}[/latex] x 100 ≈ 13% less
2. In year 2014, A expended 10 lakh more than B. Find what is the approximate percentage profit of B in the same year?
A. 23%
B. 25%
C. 35%
D. 20%
E. 27 %
Answer: Option A
Explanation:
Required percentage profit = [latex] \frac{590 - 480} {480}[/latex] x 100 ≈ 23%
3. What was the average income amount (in lakh) of A and B together in year 2013 if percentage profit earned by A was 16% and that of B was 17%?
A. 76[latex] \frac{7} {7}[/latex]%
B. 68[latex] \frac{4} {7}[/latex]%
C. 87[latex] \frac{4} {7}[/latex]%
D. 78[latex] \frac{4} {7}[/latex]%
E. 74[latex] \frac{4} {7}[/latex]%
Answer: Option A
Explanation:
Income of A in 2013 = [latex] \frac{16 x 730} {100}[/latex] + 370 = 429.2 lakh
Income of B in 2013 = [latex] \frac{17 x 380} {100}[/latex] + 380 = 446.2 lakh
∴ Average income = [latex] \frac{873.8} {2}[/latex] = Rs. 436.9 lakh
