Question

5+5=1025 6+6=3612 7+7=1449 8+8=6416 10+10?=?

Answer 1

hope this is the correct answer :
10+10=20100

Answer 2

10+10 = 10020

Given,

5+5=1025

6+6=3612

7+7=1449

8+8=6416

To Find,

10+10=?

Solution,

Among all the given sets of equations, we can find a simple logical reason for the results.

While examining those equations, it is of the form

a+a is obtained by combining the digits of b and c respectively, if a is odd and

a+a is obtained by combining the digits of c and b respectively, if a is even

Here, a is a natural number

b = a + a

c = a × a

We have to find 10 + 10 using this logic

10 is an even number

b = 10 + 10 = 20

c = 10 × 10 = 100

Therefore, 10 + 10 is obtained by combining the digits of c and b respectively

⇒ 10 + 10 = 10020
