Kajal spends 55% of her monthly income on grocery, clothes and education in the ratio of 4 : 2 : 5 respectively. If the amount spent on clothes is Rs.5540/-, what is Kajal’s monthly income?
Let the monthly income of Kajal be 100k
It is given that she spent 55% of the monthly income on grocery, clothes and education in the ratio of 4 : 2 : 5 respectively
i.e she spent 55k on grocery, clothes and education in the ratio of 4 : 2 : 5 respectively.
Amount spent on clothes = $$\ \frac{\ 2}{11}\times\ 55k$$
10k = 5540 (given)
So 100k = 55400
Monthly income = 100k = 55400
A is the correct answer.
