Question
The incomes of Arjun, Kabir, and Lakshya are in the ratio
15:10:9, and their savings are in the ratio 6:4:3. If Kabir saves Rs. 16,000, which is 40% of his income, what is Lakshya’s total spending?Solution
ATQ,
Income of Kabir = 16000 ÷ 0.4 = Rs. 40,000
Income of Lakshya = 40000 × (9/10) = Rs. 36,000
Saving of Lakshya = 16000 × (3/4) = Rs. 12,000
Expenditure of Lakshya = 36000 - 12000 = Rs. 24,000
