Nupur invests Rs. 89856, which is 26% of her annual income, in mutual funds. What is her monthly income ?

Answer: Option B

Let Nupur's annual salary be Rs. x
Then, 26% of x = 89856
⇒ $$\frac{26x}{100}$$ = 89856
⇒ x = $$\frac{89856\times 100}{26}$$
⇒ x = 345600
∴ Nupur's monthly income :
= Rs. $$\frac{345600}{12}$$
= Rs. 28800
