Expenditure of a person is 50% more than his savings. His income increases by 15% and expenditure also increased by 21%. If his savings increases by 240, then find his initial income.

10000

At 50% ⇒ Saving : Expenditure = 2 : 3.

Savings → x% = 15 - 9 = 6% = 240 (given)

Therefore, Savings = 4000

Now,

⇒ Exp. + Savings = Income

⇒ 3R + 2R = 5R

⇒ 2R = 4000

Thus, Income = 5R = 10000
