expenditure is 120 percent of M’s expenditure. If L’s income is 180 percent of M’s expenditure, then what is the respective ratio of L’s savings and M’s savings?Solution
ATQ, Let M expenditure = x L expenditure = 120% of x = 1.2x L income = 180% of x = 1.8x L saving = 1.8x - 1.2x = 0.6x L income = 125 % of M income M income = 1.44x M saving = 0.44x The ratio of the saving of L and M = 0.6x : 0.44x or 15:11
