Question

. 1z3z6 is divisible by 11. Find the value of z.

Answer 1

Answer:

z= 5

Step-by-step explanation:

While checking the divisibility rule of 11 z+z subtracted from 1+3+6 shud give either 0 or a number that is divisible by 11 .

1+3+6= 10

z cannot be 1  as 1+1= 2 .

2+ 10 =12 not equal to 0/ multipe of 11

so it is 5

5+5=10

10-10= 0
