A sum was put at simple interest at a certain rate for 3 years. Had it been put at 2% higher rate, it would have fetched Rs 360 more. Find the sum.

A sum was put at simple interest at a certain rate for 3 years. Had it been put at 2% higher rate, it would have fetched Rs 360 more. Find the sum.

A. Rs.4000
B. Rs.9000
C. Rs.5000
D. Rs.6000
Let sum = P and original rate = R. Then
[(P * (R+2) * 3)/100] – [ (P * R * 3)/100] = 360
3P*(R+2) – 3PR = 36000
3PR + 6P – 3PR = 36000
6P = 36000
P = 6000

In how many different ways can six players be arranged in a line such that two of them, Asim and Raheem are never together?

In how many different ways can six players be arranged in a line such that two of them, Asim and Raheem are never together?

A. 120
B. 240
C. 360
D. 480
Explanation:
1. As there are six players, So total ways in which they can be arranged = 6!ways =720.
A number of ways in which Asim and Raheem are together = 5!x2 = 240.
Therefore, Number of ways when they don’t remain together = 720 -240 =480.

If Rs. 7500 are borrowed at C. I at the rate of 4 % per annum then after 2 years, the amount to be paid is_______?

A. Rs. 8082
B. Rs. 7800
C. Rs. 8100
D. Rs. 8112
Explanation:
Amount = Rs. [7500 (1 +4/100)2]
= Rs. [7500 × 26/25 × 26/25] = Rs.8112

The average of 18 observations was calculated and it was 124. Later on it was discovered that two observations 46 and 82 were incorrect. The correct values are 64 and 28. The correct average of 18 observations is___________?

The average of 18 observations was calculated and it was 124. Later on it was discovered that two observations 46 and 82 were incorrect. The correct values are 64 and 28. The correct average of 18 observations is___________?

A. 123
B. 137
C. 121
D. 122
Sum of 18 observations = 18×124 =2232
Correct sum of 18 observations = 2232-46-82+64+28
= 2196
Therefore, Correct average =2196/18 = 122
