Question
A sum of Rs. 9,200 was divided between 'A' and 'B' such
that the amount received by 'B' was 30% more than that by 'A'. If 'A' and 'B' spent 10% and 25% of the respective amounts received by them, then find the sum of amounts spent by 'A' and 'B' together.Solution
Let the amount received by βAβ = Rs. β10xβ Then amount received by βBβ = 10x Γ 1.3 = Rs. β13xβ we have, 10x + 13x = 9200 So, x = 9200 Γ· 23 = 400 So, amount received by βAβ = 10 Γ 400 = Rs. 4,000 Amount received by βBβ = 13 Γ 400 = Rs. 5,200 Amount spent by βAβ = 4000 Γ 0.1 = Rs. 400
Amount spent by βBβ = 5200 Γ 0.25 = Rs. 1,300 So, required sum = 400 + 1300 = Rs. 1,700
