Answer 2

Hiii. ......friend

The answer is here
If a number is divisible by 9. Then the sum of the digits of the number should be divisible by 9.

a) 149*87.

=> 1+4+9+8+7+ *

=> 29+ *

=>The nearest and greatest multiple of 9 for 29 => 36.

So, 29+ * => 36.

* = 36-29 => 7.

So, The * is replaced by 7 to make it divisible by 9.


b) 54*5320

=> 5+4+* +5+3+2+0

=> 19+ * .

The nearest and greatest multiple of 9 near 19 => 27.

=> 19+ * => 27.

=> * =27-19 => 8.

So, The * is replaced by 8 to make it divisible by 9.
