Find the value of '?'

A) 166251 B) 166259
C) 166252 D) 166253
 
Answer & Explanation Answer: C) 166252

Explanation:

Given 92613 x 62742241 = ? + 89

 

Using unit digit method,

 

On LHS,

 

1 x 1 x 1 = 1

 

sqrt of last digit 1 => it must end with either 9 or 1

 

so now

 

1 x 1 = 1

 

1 x 9 = 9

 

On RHS,

 

? + 89

 

=> ? = ...1 - 89 = last digit is 11- 9 = 2

 

or

 

=> ? = ...9 - 89 = last digit is 9 - 9 = 0

 

Here in the options last digit 2 is option C.
