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.

@Balaji,
All numbers in that option are divisible by 11 and option B. And option D are also divisible both 11 and 8 then how you can say that above method is correct?

I agree with @Vasanthi because give no should be divisible by both 11 and as well as 8. But we should take the rule for divisibility of 8 only not 4*2. i.e. no formed by last 3 digit no should be divisible by 8.

4 digits no 9999 k. But how is it 113, 88, 119, 319? Please explain sir.

9944.
(9+4)-(9+4)=0 or div by 11.
Last 3 digit 944 div by 8.
So it is div by 88.
(9+4)-(9+4)=0 or div by 11.
Last 3 digit 944 div by 8.
So it is div by 88.

Another simple method.
Divide the largest number by the given number.i.e 9999/88 which is equal to 113.625
Now multiply the exact number (number before the .(dot) i.e 625 (113*88). The result would be 9944.
Also we are taking 9999 because the largest number from 01 to 1000 (the numbers given are between 01 to 1000) is 9999.

The largest 4 digit number is 9999. As we have to check largest 4 digit number divisible by 88 we can exclude options b and d. 9988 is not divisible by 8. So answer is 9944.

I can't understand why are you take 9999.

To akansha it is a correct method.formula of divisible by 11 is odd place no=even place number and by 8 is the sum of first 3 digit must be divisible by 8.Here greatest number is given 9944 which fulfil the two condition above.Although others are also fulfil the conditions but they are not greatest.
