Question
'S' earns 50% more than 'T'. 'S' and 'T' save 45% and
25% of their incomes. If the gap between their expenses is Rs. 1,200, how much does 'S' save?Solution
ATQ,
Let the income of 'T' be Rs. '100n'
Income of 'S' = 1.5 Ă— 100n = Rs. '150n'
Expenditure of 'S' = 0.55 Ă— 150n = Rs. '82.5n'
Expenditure of 'T' = 0.75 Ă— 100n = Rs. '75n'
So, 82.5n - 75n = 1200
Or, 7.5n = 1200
Or, 'n' = 160
Savings of 'S' = 150n - 82.5n = 67.5n = 67.5 Ă— 160 = Rs. 10,800
