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

x = share in NSC.
y = share in PPF.
Now,
x+y = 150000........eqn 1.
Also x/3 = y/2.
Then,
x = 3y/2.
Substitute in 1,
3y/2+y=150000.
Solving it.
y = 60000.
y = share in PPF.
Now,
x+y = 150000........eqn 1.
Also x/3 = y/2.
Then,
x = 3y/2.
Substitute in 1,
3y/2+y=150000.
Solving it.
y = 60000.

There is another way to solve the problem
Say, PPF = x then,
NSC = 1.5x
Total savings,
1.5x + x = 150000
2.5x = 150000
x = 150000/2.5
x = 60000
Say, PPF = x then,
NSC = 1.5x
Total savings,
1.5x + x = 150000
2.5x = 150000
x = 150000/2.5
x = 60000

Hey here goes very easy way.
N+P = 150,000 given.
1/3(N+P) = 1/3(150,000).
We know 1/3N = 1/2P Substitute.
1/2p+1/3p = 50,000.
p = 60,000.
N+P = 150,000 given.
1/3(N+P) = 1/3(150,000).
We know 1/3N = 1/2P Substitute.
1/2p+1/3p = 50,000.
p = 60,000.

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.

x/3+x/2= 1,50,000(total saving),
5x/6= 1,50,000.
x= 1,50,000*6/5 = 1,80,000.
ppf = x/2 so ppf may be 1,80,000/2 = 90,000.
5x/6= 1,50,000.
x= 1,50,000*6/5 = 1,80,000.
ppf = x/2 so ppf may be 1,80,000/2 = 90,000.

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.

Let,
3 parts of NSC + 2 parts of PPF = 150000.
Total 5 parts = 150000,
1 part = 30000,
2 parts of PPF = 60000.
3 parts of NSC + 2 parts of PPF = 150000.
Total 5 parts = 150000,
1 part = 30000,
2 parts of PPF = 60000.

One-half means 2 part,
One-third means 3 part, then 2 + 3 = 5,
=> 150000/5 * 2 = 60000.
One-third means 3 part, then 2 + 3 = 5,
=> 150000/5 * 2 = 60000.

Nps/3=ppf/2
Npf/Ppf = 3/2
Npf :Ppf = 3:2
Ppf = 2/5*1,50,000 = 60000.
Npf/Ppf = 3/2
Npf :Ppf = 3:2
Ppf = 2/5*1,50,000 = 60000.
