Samuel had four times as many stamps as Mitchell at first. When both added an equal number of stamps to their collection, Mitchell had 60 stamps and Samuel had thrice as many stamps as Mitchell. How many stamps did each of them add to their collection?
Ans: 22

Pls help!

At first :
S --- 4 units
M --- 1 unit

later :
Added same number of stamps, let it be X
S ---- X + 4 units= 3 x 60 = 180
M --- X + 1 unit = 60

Therefore,
3 units ---- 180 - 60 = 120
1 unit ---- 120 / 3 = 40

Added stamps : 60 - 40 = 20 stamps
