5 × 2 a multiple of 11?

###### Advertisements

#### Solution

Sum of a digit in even place = x

and sum of the digits in odd place = 5 + 2 = 7

Difference of the sum of the digits in even places and in odd places = x – 7

5×2 is a multiple of 11

⇒ x – 7 = 0, 11, 22,

⇒ x = 7, 18, 29,

Since, x is a digit

x = 7
