What will be the difference between simple and compound interest at 10% per annum on a sum of Rs. 1000 after 4 years?

What will be the difference between simple and compound interest at 10% per annum on a sum of Rs. 1000 after 4 years?

A. Rs. 31
B. Rs. 32.10
C. Rs. 40.40
D. Rs. 64.10
Explanation:
S.I. = (1000 * 10 * 4)/100 = Rs. 400
C.I. = [1000 * (1 + 10/100)4 – 1000] = Rs. 464.10 Difference = (464.10 – 400) = Rs. 64.10

What percent of 125 is 16?

What percent of 125 is 16?

A. 10 2/5%
B. 12 3/5%
C. 11 1/5%
D. None of these
Explanation:
Let the required percentage be x%.
x% of 125 = 16 => x/100 * 125 = 16
=> x = 1600/125 = 64/5 = 12 4/5

If 35% of a number is 12 less than 50% of that number, then the number is_________?

If 35% of a number is 12 less than 50% of that number, then the number is_________?

A. 40
B. 50
C. 60
D. 80
Explanation:
Let the number be x. Then,
50% of x – 35% of x = 12
50/100 x – 35/100 x = 12
x = (12 * 100)/15 = 80.

If the C.I. on a sum for 2 years at 12 1/2 % per annum is Rs. 510, the S.I. on the same sum at the same rate for the same period of time is________?

If the C.I. on a sum for 2 years at 12 1/2 % per annum is Rs. 510, the S.I. on the same sum at the same rate for the same period of time is________?

A. Rs. 400
B. Rs. 450
C. Rs. 460
D. Rs. 480
Explanation:
Let the sum be Rs. P. Then,
[P(1 + 25/(2 * 100))2 – P] = 510
P[(9/8)2 – 1] = 510.
Sum = Rs. 1920
So, S.I. = (1920 * 25 * 2) / (2 * 100) = Rs. 480
