Question

If the number 7254*98 is divisible by 22. then the digit at * is?

Answer 1

7+5+x+8-2+4+9
=20+x-15
if we put x =4 we get the answer 11 which is divisible by 11
and divisibility of 2 is unit place should consists of 0,2,4,6,8 so for the divisibility of 22 should satisfy both 11 and 2 s divisibility so if we put x=4 it satisfies the divisibility of 11
