If 6 + 2 = 20, 8 + 3 = 35, then 10 + 5 = ?

Show answer & explanation

Correct answer: B

Explanation

6 + 2 = 20

8 + 3 = 35

6 + 2 = 6 × 2 + (6 + 2) = 20

But,

8 + 3 = 8 × 3 + (8 + 3) = 35

So the rule is:

a + b = ab + (a + b)

Now,

10 + 5 = 10 × 5 + (10 + 5)

= 50 + 15

= 65

Correct answer: 65
