Step-by-step explanation:
Here let A have x money
and B have y money
then here,
x-50= y+50
=> y+50= 2(x-50) .....(i)
and
y-20= x+20
=> x+20= 3(y-20)......(ii)
in equation (i)
y+50= 2x-100
=> y= 2x-100+50
=> y= 2x-50
Putting y value in equation (ii)
x+20= 3{(2x-50)-20}
=> x +20= 3{2x-70}
=> x +20 = 6x-210
=> 210+20= 6x-x
=> 5x = 190
=> x = 190/5
=> x = 38
Then y = 2x-50
= > y = 2*38-50
=> y = 76-50
=> y = 26
Thus, A have Rs 38 and B have Rs 26
