Question

A sum of rs1240 is distributed among A, B and C that the ratio amount receiver by A and B is 6:5 and that of B and C is 10:9 respectively. find the share of C ?
(a) 480 (b) 360 (c)400 (d) 690​

Answer 1

Given, A : B = 6 : 5

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

Answer 2

b) 360

A : B B : C

6 : 5 10 : 9

12 : 10 : 9

=> 12x + 10x + 9x => 31x

31x = 1240

x = 40

∴ Share of C=9×40=360
