Correct Answer: 16%
Solution : Given, A's share = 25% of Manoj's income B's share = Rs. 2208 = A's share - 1542 Let Manoj's income be $x$ ⇒ A's share = $\frac{25}{100}x$ = $0.25x$ Let B's decided share be $y$ ⇒ B's share = $2208$ = $\frac{92}{100}y$ ⇒ $y = \frac{2208}{0.92}$ ⇒ $y =$ Rs. 2400 According to the question, 2208 = A's share – 1542 ⇒ A's share = Rs. 3750 ⇒ $0.25x = 3750$ ⇒ Manoj income = $x$ = Rs. 15000 ⇒ Decided percentage for B = $\frac{2400}{15000}× 100$ = 16% Hence, the correct answer is 16%.
