Answer 1

Answer:

z=5

Step-by-step explanation:

Divisibility by 11: Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number.

applying the rule here, we get

(1+3+6)-(z+z)=b (where b is nearest multiple of 11)

10-2z=b=0 (because 0 is nearest multiple of 11 less than 10)

=>2z=10

=>z=5
