Question
'A' spends 75% of his income,
while 'K' spends 80% of his income. Both of them save ₹7,500 each. The income of 'S' is one-third of the combined income of 'A' and 'K'. If 'S' spends 7/9 of his income, calculate his savings.Solution
ATQ,
Income of A = (7,500/0.25) = Rs. 30,000 Income of K = (7,500/0.2) = Rs. 37,500 Income of S = (1/3) × (30,000 + 37,500) = Rs. 22,500 Therefore, savings of S = (2/9) × 22,500 = Rs. 5,000
