One-third of Rahul's National Savings Certificate investments is equal to one-half of his PPF savings. How much has he saved in the Public Provident Fund if his entire savings are Rs. 1,50,000?
A. Rs. 30,000 B. Rs. 50,000 C. Rs. 60,000 D. Rs. 90,000
Explanation: Allow for Rs. x in N.S.C. and Rs. (150000 - x) in P.P.F. savings, respectively. Then,1/2 Equals 1/3 x (150000 - x),75000 = x/3 + x/2,75000 = 5x/6,75000 x 6/5 = 90000 .Public Provident Fund (PPF) savings = Rs. (150000 - 90000) = Rs. 60000.
