Hi;
Good Quiz indeed!!! . One error noticed
Please see the following problem:

What is the sum of all three digit positive integers, the sum of whose digits is a multiple of 3?
900
330300
330000
329199
328900

The required sum is of all numbers from 100 to 999 the sum of whose digits is a multiple of three.

This sum is 300*(102+999)/2=165150.

Hi Shaji

Thanks a tonne for pointing the error. I forgot to divide the total by two in all of the answer choices while computing the sum of numbers in an A.P.

Will have the error rectified in the quiz.

Thanks again
