Question

find missing no.in this figure
​

Answer 1

5,6,4 are in circumference of 1 st triangle

6^2 - 5^2 = 36 -25 = 11

Now 4^2 -11 = 16 -11 = 5

5 is in the triangle 1 st

2) 6,7,5 in circumference

7^2 - 6^2 = 49 -36 = 13

5^2 -13 = 25 - 13 = 12

Now reverse 12

So its 21

Which is in triangle 2

So

3) 4,8,10 is in circumference

8^2 -4^2 = 64 -16 = 48

10^2 -48 = 100 -48 = 52

Reverse 52

So its 25

Hence 25 is Ans
