Correct option is C
Given:
L's income = 125% of M's income
L's expenditure = 120% of M's expenditure
L's income = 180% of M's expenditure
Formula Used:
Savings = Income − Expenditure
Solution:
Let M's expenditure be x. Then:
L’s income = 1.8x
L’s expenditure = 1.2x
From the first condition (L’s income = 1.25 × M’s income):
M’s income = = 1.44x
M’s savings = 1.44x − x = 0.44x
L’s savings = 1.8x − 1.2x = 0.6x
Ratio of L's savings to M's savings:
Ratio =
Thus, the respective ratio of L's savings to M's savings is 15 : 11.
