Question

Sandeep has twice as much money as soina together they have 150how much money does soina have

Answer 1

Money with Sandeep=x
Money with Sonia=y

x+y=150 .........(1)
x=2y .........(2)


Substituting (2) in(1)

2y+y=150
3y=150
y=150/3
y=50


Substituting y=50 in (1)

x+50=150
x=150-50
x=150-50
x=100

Money with Sandeep=100
Money With Sonia=50
