Hi,

This question no need to do any calculations, we can just solve this by elimination the options.

If you know the seven tables(multiples), then it is pretty straight forward, in a hundred there are 14 multiples (7 * 14 = 98) and since the question asking for even multiples it has to be less than 14

multiples (In-fact 7 even multiples because half even and half odd). So the only answer choice has to be 7.

Also, first three digit number divisible by 7 is 105(7*15) and the last number (less than 200) is 196(28*7).

If you are looking for a standard approach, then,

To find the number of elements(if they are evenly spaced), use the below expression,

(L – A )/D + 1 = to count the number of elements

L is the last element, A is the first element and D is the common difference.

So, (196 – 105)/ 7 + 1 = 14.

Since only even numbers , so divide the above count by 2. So the answer is E(7).
