Question

The ratio of the expenditure to the saving of a family is 7:3. find the income if the expenditure is ₹6300.

Answer 1

ratio of expenditure : saving =7:3
therefore total income =
7x+3x=10x
expenditure =7x=6300
=> x =900

therefore total income = 10×900
=9000

Answer 2

LET SAVING BE X
7:3::6300:X
PRODUCT of EXTREME=PRODUCT of MEANS
7X=18900
X=18900/7
X=2700
SO INCOME =6300+2700
= 9000
