Answers 

 

1. 

Let rate = R% and time = R years.

Then, 1200 x R x R = 432
100

 12R2 = 432

 R2 = 36

 R = 6.

 

2. 

Gain in 2 years
= Rs. 5000 x 25 x 2 5000 x 4 x 2
4 100 100
  = Rs. (625 – 400)
  = Rs. 225.
 Gain in 1 year = Rs. 225 = Rs. 112.50
2

 

 

3. 

We need to know the S.I., principal and time to find the rate.

Since the principal is not given, so data is inadequate.

 

4. 

Let the principal be P and the rate of interest be R%.

 Required ratio =
P x R x 6
100
= 6PR = 6 = 2 : 3.
P x R x 9
100
9PR 9

 

 

5. 

Given : S.I. = Rs. 50.

I gives, R = 10% p.a.

II gives T = 10 years.

 Sum = 100 x S.I. = Rs. 100 x 50 = Rs. 50.
T x R 10 x 10

Thus, I and II together give the answer.

 The correct answer is (E)

 

 

6. 

Let the rate be R% p.a.

I gives, P = Rs. 8000 and T = 4 years.

II gives, S.I. = Rs. (8800 – 8000) = Rs. 800.

 R = 100 x S.I. = 100 x 800 % = 2 1 % p.a.
P x T 8000 x 4 2

Thus, I and II both are needed to get the answer.

 The correct answer is (E)

 

7. 

Let the rate be R% p.a.

I gives, P = Rs. 8000 and T = 4 years.

II gives, S.I. = Rs. (8800 – 8000) = Rs. 800.

 R = 100 x S.I. = 100 x 800 % = 2 1 % p.a.
P x T 8000 x 4 2

Thus, I and II both are needed to get the answer.

 The correct answer is (E).

 

8. 

Let the sum be Rs. x.

I gives, S.I. = Rs. 7000 and T = 7 years.

II gives, Sum + S.I. for 5 years = 2 x Sum          Sum = S.I. for 5 years.

Now, S.I. for 7 years = Rs. 7000.

 S.I. for 1 year = Rs. 7000 = Rs. 1000.
7

Thus, I and II both are needed to get the answer.

 The correct answer is (E).

 

9. 

We know that R = 100 x S.I.
P x T

Now, I give, S.I. = Rs. 4000.

II gives T = 4 years.

But, P is unknown. So, we cannot find R.

So, given data is insufficient to get R.

 The correct answer is (D).
