The expenditure of a person is 60% more than his savings. If his savings increases by 24% and expenditure decreases by 13% then his income increases by Rs.1280. Find his total expenditure.
Answer & explanation
Correct answer: option 2
Income = Expenditure + Savings
⇒ Exp. : Sav. = 160 : 100 = 8 : 5
ATQ,
⇒ (-13%) of 8R + (24%) of 5R = 1280
⇒ -(13 × 8) R + (24 × 5) R = 128000
⇒ 16 R = 128000
⇒ 1 R = 8000
Hence, Expenditure = 8R = 8 × 8000 = Rs.64000
