The rule for divisibility by 9 is similar to divisibility rule for 3. That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.
Example: Consider 78532, as the sum of its digits (7+8+5+3+2) is 25, which is not divisible by 9, hence 78532 is not divisible by 9

Additive inverse refers to any number that when added to the original number gives the result as zero. For instance, the additive inverse of 8 is -8 as 8 + (-8) = 0. It is possible to get the additive inverse of negative numbers too. For example, the additive inverse of -10 will be 10 as -10 + 10 = 0.

Time taken by Ravi to do the work = 12 days
Time taken by Leena to do the work = 8 days
So,
Work done by Ravi in 1 day = 1: 12
Work done by Leena in 1 day = 1: 8
So,
Work done by Ravi and Leena in 1 day = 1: 12 + 1: 8 = (2 + 3): 24 = 5: 24
Thus,
Anil and Ankur can do the work in 24:5 days, i.e., 4(4/5) days.
