Question

212×5 is a multiple of 4 and 11 find the value of x

Answer 1

Answer:

Step-by-step explanation:

212x5 is multiple of 3 and 11 . It means 212x5 is divisible by 3 and 11 both.

Divisibility text of 11:- the difference between the sum of digits at the even

position and the sum of digits at odd position is 0 or 11

Now,

(2 + 1 + 2 + x + 5 ) = (10+x) is divisible by 3 _________________(1)

and (1 + x) - (2 + 2 + 5) = 0 or divisible by 11

x - 8 = 0 or divisible by 11

x = 8 or 8 + multiple of 11 _____________(2)

From eqns (1) and (2)

Hence, minimum value of x = 8

Answer 2

YOUR answer is x=8 after the proseeger
