1.  One-third of Rahul's savings in National Savings Certificate is equal to one-half of his savings in Public Provident Fund. If he has ₹ 1,50,000 as total savings, how much has he saved in Public Provident Fund ?
A. ₹ 30,000
B. ₹ 50,000
C. ₹ 60,000
D. ₹ 90,000

Answer: Option C

Explanation:

Let savings in N.S.C and P.P.F. be ₹ x and ₹ (150000 - x) respectively. Then,

1 x = 1 (150000 - x)
3 2

x + x = 75000
3 2

5x = 75000
6

x = 75000 x 6 = 90000
5

Savings in Public Provident Fund = ₹ (150000 - 90000) = ₹ 60000
