The largest no 9999/88 = 113.
And to compared to the values, /88 = 113.
9944/88 = 113.
9768/88 = 111.
9988/88 = 113.5.
8888/88 = 101.
So, they equal values to show the result in 9944.

Why cannot we do it by splitting the number?
88 = 11 * 4 * 2.
88 = 11 * 4 * 2.

9999/88 = 113.625
Take the integer part only i.e 113 and multiply it by 88 (113 * 88 = 9944)
So, 9944 is the largest 4 digit no exactly divisible by 88 simple.

@Vasanti is right.
9999/11 = 909, 909/8 = 113 and reminder is 5.
Now multiply 5 by 11, because 88 has been split into 11 and 8 and 5*11 = 55, 9999-55 = 9944 is your answer.
9999/11 = 909, 909/8 = 113 and reminder is 5.
Now multiply 5 by 11, because 88 has been split into 11 and 8 and 5*11 = 55, 9999-55 = 9944 is your answer.

Why can't we do it by splitting the number?
88 = 11*4*2.
Why can't we take the largest number that is divisible by 11, 4 & 2?
(This method was used to solve problem no:6).
88 = 11*4*2.

88=11*8.
If 9944 is divisible by 8 and 11. It is also divisible by 88.
9944/8=1243, 9944/11=94.
So it is divisible by 88.
If 9944 is divisible by 8 and 11. It is also divisible by 88.
9944/8=1243, 9944/11=94.
So it is divisible by 88.
