Question

Divide120 into two aprts such that 2/3 of one part is equal to 2/5 of the other part

Answer 1

Answer:

let the one part be x

then the other part is 120-x

so according to the situation

2/3×x=2/5(120-x)

2x/3=240/5-2x/5

2x/3+2x/5=48

take LCM

that will be 15

so equation will be...

10x/15+6x/15=48

16x/15=48

x=48x15/16

x=45

so one part is 45 and other is 120-45=75
