Two sets A and B each have three numbers in A.P., each summing to 15. Their common differences D and d satisfy D − d = 1 , d 0 . If p and q are the respective products of the numbers in A and B, p/q

Question

Two sets A and B each have three numbers in A.P., each summing to 15. Their common differences D and d satisfy $D - d = 1, d > 0$ . If p and q are the respective products of the numbers in A and B, p/q=7/8. Find q.

Options:

Answer:

B

Solution:

With $d = 1$ and $D = 2, B = {4, 5, 6}$ ; hence $q = 4 \times 5 \times 6 = 120$ .
