Question

6. Write a digit in the blank space of each of the following numbers so that the number
formed is divisible by 11:
(a) 92_389 (b) 8_9484
​

Answer 1

Step-by-step explanation:

(a) let there is x in blank space

By divisibility of 11,

9+x+8 = 17+x

2+3+9 = 14

17+x-14 = 11

x = 8

(b) 8+9+8 = 25

x+4+4 = x+8

x = 6
