Question

Divide rupees 414 into three such parts that first one is 2/3 of the second one and the ratio between second and third is 5 : 7.​

Answer 1

Answer:

let the second one is x

first one is 2x/3

let the third one is z

x:z = 5:7

7x=5z

2x/3+x+7x/5=(10x+15x+21x)/15=46x/15=414

x=135

the three parts are 90,135,198
