Bhanu's income. If Arjun and Bhanu spend 75% and 80% of their respective incomes, determine the ratio of Arjun's savings to that of Bhanu.Solution
ATQ, Let, income of ‘Arjun’ and ‘Bhanu’ be Rs. 'a' and Rs. 'b' respectively. So, 0.6a = 0.5b Or, a/b = 5/6 Let, a = 5k, b = 6k Savings of ‘Arjun’ = (1 – 0.75) × 5k = Rs. (5k/4) Savings of ‘Bhanu’ = (1 – 0.8) × 6k = Rs. (6k/5) Required ratio = (5k/4):(6k/5) = 25:24
