Question

the ratio of the income to the expenditure is as 9:8 find the savings if the income is ₹1800

Answer 1

let the ratio be X,then
income=rs.9x and expenditure =rs.8x
a/q,
9x=1800
so, x=200.
expenditure =8x = 8*200=1600
saving = income - expenditure
= rs.1800-rs.1600
=rs.200
thus, saving= rs. 200

Answer 2

The ratio to income to expenditure is 9:8

∴let the income be 9x and expenditure be 8x.

saving = income - expenditure

∴saving = 9x - 8x = x

income = 9x

∴ 1800 = 9x

∴ x = 200

∴ savings = 200
