GMAT Problem Solving (PS) | Re: How many two-digit whole numbers yield a remainder of 3 when divided

take the lcm of 4 and 10. which is 20.

now take the first common number from both the patters 10k+3 and 4q+3, which is 3.

now common series is 20n+3 and we will get 0,23,43,63 and 83.

since we have been asked only 2 digit numbers, the answer is 4.

option D is the correct asnwer.
