Can we solve it using the remainders concept :
I started off with :
1) 24+13 = mq+1
24 = mq-12
2) 24+7 = np+1
24 = np-6
Taking both together :
0 = mq-np-6
After this I got lost.....

You are using too many variables. Use only as many as you actually need.
Question says 24/n = an integer
Statement 1: 24+13 = 37 gives remainder 1. This means 36/n is an integer. Common factors of 24 and 36 are 3, 4, 6 which can equal n. Hence, not sufficient.
Statement 2: 24+7 = 31 gives remainder 1. This means 30/n is an integer. Common factors of 24 and 30 are 3, 6 which can equal n. Hence not sufficient.
Together, n can be 3 or 6. So answer (E)
