Solution

The correct option is E Statement (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.

Answer=option (e)

If the three terms

AP 1 = a-d,a and a+d

AP 2 = A, A-D and A+D and D= d+1

S= 3a = 3A= 15. a=A=5

Also, P/P1= {a(a2-d2)}/ {(A2-D2)} = 7/8

It is not possible to get a unique solution, even after using both statements. Answer is

option (e)
