Question

Divide 120 into 2 parts such that 2/3 of one part is equal to 2/5 of the other part

Answer 1

☸ Required Answer is ⬇⬇ ⬇⬇ ⬇

let one part be x

then, other part will be 120-x

According to Question,

2/3x=2/5(120-x)

2/3x=48-2/5x

multiply both sides by 15.

15*2/3x=15*48-15*2/5x

10x=720-6x

10x+6x=720

16x=720

x=720/16

x=45

hence,

one part is 45

and

another part will be

(120-45)=75

Answer 2

let one part be x

another part= 120-x

A.T.Q,

2/3x=2/5(120-x)

2/3x=48-2/5x

15*2/3x=15*48-15*2/5x

10x=720-6x

16x=720

x=45

1st part=45

2nd part= 120-45=75
