Question : Bhanu spends 20% of his monthly salary on rent, 10% on stationery, 14% on transport, 18% on electricity, and the balance of ₹1,520 on remaining items. What is the monthly salary of Bhanu?

₹ 10,000

₹ 5,000

₹ 4,000

₹ 2,000

Solution: $\require{cancel}$

ভানুর বাকি আয়ের 100-(20+10+14+18) = 100 - 62 = 38% মানে ₹1,520 টাকা।

∴ ভানুর মাসিক আয় = $ \cfrac{100}{\cancel{38}} \times \cancelto{40}{1520} $
$ = 100 \times 40 $
$ = 4,000 $ টাকা।
