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 Rs. 1,50,000 as total savings, how much has he saved in Public Provident Fund ?
Answer: Option
Explanation:
Let savings in N.S.C and P.P.F. be Rs. x and Rs. (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 = Rs. (150000 - 90000) = Rs. 60000

Let his savings in NSF be = x.
Let his savings in PPF be = y.
ATQ
X/3=y/2.
On solving yhis we get
2x =3y,
2/3x =y,
Now
X+y = 150000,
Putting the value of y as solved above.
X+2/3x = 150000,
X = 90000,
Y = 150000-90000 = 60000.
Let his savings in PPF be = y.
ATQ
X/3=y/2.

Now
X+y = 150000,

X+2/3x = 150000,
X = 90000,
Y = 150000-90000 = 60000.

N/3 = P/2.
Therefore, N = 3/2P.
Given N+P = 1,50,000,
3/2P+P = 1,50,000,
5/2P = 1,50,000,
Therefore, P = 1,50,000 * 2/5 = 60,000.
Therefore, N = 3/2P.
Given N+P = 1,50,000,
3/2P+P = 1,50,000,
5/2P = 1,50,000,
Therefore, P = 1,50,000 * 2/5 = 60,000.

Solution:
1/3n(national savings certificate) = 1/2p(public provident fund).
n/p = 3/2,
n:p = 3:2.
So, Total savings/(ratio total),
150000/5 = 30000,
Then, p = 2(30000).
= 60000.
1/3n(national savings certificate) = 1/2p(public provident fund).
n/p = 3/2,
n:p = 3:2.
So, Total savings/(ratio total),
150000/5 = 30000,
Then, p = 2(30000).
= 60000.

Ratio is the best method to solve.
Take the lcm for 2 and 3 is 6.
Therefore A s part is 3 B s part is 2.
Total part is 5.
Divide the total amount /5.
One part is equal to 30000.
B's part 2*30000 = 60000.
Take the lcm for 2 and 3 is 6.

Divide the total amount /5.
One part is equal to 30000.
B's part 2*30000 = 60000.

1/3 A=1/2 B and A=3B/2.
A+B=1, 50,000.
3B/2 +B =1,50,000,
5B/2 = 1,50,000,
B = 3,00,000/5 =60, 000.
B = 60,000.
A+B=1, 50,000.
3B/2 +B =1,50,000,
5B/2 = 1,50,000,
B = 3,00,000/5 =60, 000.
B = 60,000.
