Question

What number will come in place of question mark?

Answer 1

logic  

in first triangle  

logic is  

7² - (4²+3²)  

= 49 - 25  

= 24

now reverse the digits  

we get 42  

In same way use this logic in 2nd triangle  

8² - (6²+3²)  

= 64 - 45  

= 19  

reverse the digits  

we get 91  

in same way use this in 3rd triangle  

9² - (5² + 3²)  

81 - 34  

= 47  

reverse the digits  

we get 74  

so required answer for 3rd triangle is 74 i.e. option D
