1. A sum of Rs. 1240 is distributed among A, B and C such that the ratio of amount received by A and B is 6 : 5 and that of B and C is 10 : 9 respectively. Find the share of C ?
B : C = 10 : 9
A : B = 6 : 5 (multiply with 2)
i.e. A : B = 12 : 10
∴ A : B : C = 12 : 10 : 9
⇒ 12x + 10x + 9x = 1280
⇒ x = 40
∴ Share of C = 9 × 40 = 360
Solution:
Given,A : B = 6 : 5B : C = 10 : 9
A : B = 6 : 5 (multiply with 2)
i.e. A : B = 12 : 10
∴ A : B : C = 12 : 10 : 9
⇒ 12x + 10x + 9x = 1280
⇒ x = 40
∴ Share of C = 9 × 40 = 360
