The earnings of 'Amit' and 'Bittu' are in the ratio 5:8.
Their respective expenditures are in the ratio 4:7. If the gap between their savings is Rs. 6,000, determine the income of 'Amit'.Solution
ATQ, Let the income of ‘Amit’ and ‘Bittu’ be Rs.‘5a’ and Rs.‘8a’, respectively. And, let the expenditure of ‘Amit’ and ‘Bittu’ be Rs.‘4b’ and Rs.‘7b’, respectively. ATQ; (8a – 7b) – (5a – 4b) = 6000 Or, 3a – 3b = 6000 So, (a – b) = 2000 We can’t uniquely determine the values of ‘a’ and ‘b’ hence the answer cannot be determined.
