Given :- A man saves 1950. If the ratio of his savings to his expenditure is 20 : 17. find his earnings.
Solution :-
Let us assume that, man saves Rs.20x and expenditure is Rs.17x .
so,
→ 20x = 1950
dividing both sides by 20,
→ x = 97.5
then,
→ Man earning = His saving + His Expenditure .
→ Man earing = 20x + 17x
→ Man earning = 37x
putting value of x we get,
→ Man earing = 37 * 97.5
→ Man earing = Rs.3607.5 (Ans.)
Hence, his earning is Rs.3607.5.
