**Answer This Question**

Pls help me thank you sir/mdm

David at first : 11 units

Difference = 11 - 8 = 3 units

Ahmad after giving away : 9 units

David after giving away : 14 units

Difference = 14 - 9 = 5 units

Since they gave away equal number of toy cars, their difference before giving away and after giving away is the same. So make the number of units the same.

5 x 3 = 15

3 x 5 = 15

So the difference is actually 15 units.

So actually, Ahmad at first

= 8 x 5 = 40 units

Ahmad after giving away

= 9 x 3 = 27 units

40 - 27 = 13

He gave away 13 units.

Percentage Ahmad gave away

= 13/40 x 100%

= 32.5%
