Question

Ask your friend rite — W down your A age. dd 5 to it. Multiply the sum by 2. Subtract 10 from it. Next, divide it by 2. What do you get?

Sum

Solution

Let the age of my friend be 9 years.

Adding 5 to it, we get

9 + 5 = 14

Multiplying this sum by 2, we get

14 × 2 = 28

Subtracting 10 from 28, we get

28 − 10 = 18

Dividing it by 2, we get

18 ÷ 2 = 9

The answer is the same as my friend’s age.
