Total unchanged.

Total units = 5 + 7 = 12

Since they had equal amount of $ at first,
number of units should be the same at first.


12 units ÷ 2
= 6 units

Ratio for Before = 6 : 6
Ratio for After = 5 : 7

So we can see that Abdul gave 1 unit to Ben

So 30 stickers = 1 unit

Both had 6 units each at first.

6 x 30 = 180

So Abdul had 180 stickers at first
(And so did Ben)
