Let rate = R% and time = R years.
Then,  1200 x R x R  = 432  
100 
12R^{2} = 432
R^{2} = 36
R = 6.
2.
Gain in 2 years 
 
= 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 = 
 =  6PR  =  6  = 2 : 3.  
 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).
