Question

If 48 = 24, 32 = 11, 91 = 82 then 42 = ?

Answer 1

Given: 48 = 24, 32 = 11, 91 = 82

To find: 42 = ?

Solution:

• 48 = 4² + 8 = 16 + 8 = 24

• 32 = 3² + 2 = 9 + 2 = 11

• 91 = 9² + 1 = 81 + 1 = 82

From the first three terms, it can be seen that the resulting number is the sum of the square of the first digit and the second digit itself.

• To find what 42 would be, simply find square of the first digit 4 and add it with the second digit 2.

Then, 42 = 4² + 2 = 16 + 2 = 18

Answer: 42 = 18.
