Question

Alex bought 6 pizzas for his birthday party. Each pizza has 4 slices. Out of all, 3 slices are eaten by Alex before the party. If he invited 7 friends, how many slices will each of his friends get ?

• A. 3
• B. 4
• C. 1
• D. 2

Answer 1

The correct option is A 3

Number of pizzas = 6

Number of slices in 1 pizza = 4

Total number of slices = 6 $\times$ 4
= 24

3 were eaten by Alex.

Number of slices remaining
= 24 - 3 = 21

21 is to distributed among 7 friends equally.

Lets apply repeated subtraction.

21 - 7 = 14
14 - 7 = 7
7 - 7 = 0

After 3 times of repeated subtraction 21 reduces to 0.
So, each of his friends will get 3 slices of pizza.
