Question 2 of 5
2. Question
Directions : In each of the following questions, a question followed by two statements numbered 1 and 2 are given. You are to read both the statements and then give the answer
What is the rate of interest percentage per annum?
- An amount of 6200 fetches Simple interest of Rs. 1736 in 2 yr.
- An amount of Rs. 4500 fetches compound interest of Rs. 1348.20 in 2 yr.
Correct
Answer : b
From Statement 1,
R = (SI * 100)/(P *T) = 14%
(91736 *100)/(6200 *2) = 14%
From Statement 2,
1348.2 = 4500 [ 1 +r/100]2 – 4500
1348.2 + 4500 = 4500 [1+ r/100]2
(5848.2)/(4500) = ( 1 + r/100)2
(93249/2500) = ( 1 +r/100)2
(57/50)2 = ( 1 +r/100)2
1 + (r/100) = (57/50)
(r/100 ) = (57/50)-1 = (7/50)
r = (7 *100)/50
∴r = 14%
Both statements are alone sufficient.
Incorrect
Answer : b
From Statement 1,
R = (SI * 100)/(P *T) = 14%
(91736 *100)/(6200 *2) = 14%
From Statement 2,
1348.2 = 4500 [ 1 +r/100]2 – 4500
1348.2 + 4500 = 4500 [1+ r/100]2
(5848.2)/(4500) = ( 1 + r/100)2
(93249/2500) = ( 1 +r/100)2
(57/50)2 = ( 1 +r/100)2
1 + (r/100) = (57/50)
(r/100 ) = (57/50)-1 = (7/50)
r = (7 *100)/50
∴r = 14%
Both statements are alone sufficient.

- The boat travels at the speed of 4 km/h upstream.
- The boat travels at the speed of 6 km/h downstream
Correct
Answer : d
We know that,
Speed of boat in still water

So, answer can be determined from both statements.
Incorrect
Answer : d
We know that,
Speed of boat in still water
= (Speed upstream + Speed downstream )/2
From Statements 1 and 2,
Speed = (6+4)/2 = (10/2) = 5km/h
So, answer can be determined from both statements.
