Question

. The difference between the compound interest and the simple interest on the sum for 2
the compound interest on that sum at the same rate and for the same period
years at 12% per annum is Rs 100. Find the sum.
​

Answer 1

Answer:Find the simple interest, If

P = Rs.1000, R = 20% per annum, T = 4 years.

P = Rs.600, R = 5% per annum, T = 4 months.

P = Rs.200, R = 6% per six months, T = 3 years.

P = Rs.500, R = 2% per six months, T = 5/2 years.

P = Rs.400, R = 3% per three months, T = 2 months.

P = Rs.730, R = 10% per annum, T = 120 days.

P = Rs. 3000, R = 61/4 per annum, T = period from 4th Feb to 18th Apr.

Trick to find simple interest

#2  

Find the following:

P = Rs. 100, R = 3% per annum, T = 2 year, A= ?

P = Rs. 500, R = 6% per annum, T = 4 months, A= ?

P = Rs. 400, R = 3.65% per annum, T = 150 days, A= ?

A = Rs. 540, S.I = Rs. 108 , R = 5%, T = ?

A = Rs. 1,120, R = 5%, T = 22/5 yr, S.I = ?

# Solution:

S.I = 6 ; A = S.I + principal ; A = 6 + 100 ⇒ 106

simple interest tricks

S.I = 10 ; A = S.I + P ; A = 10+500 ⇒ 510

S.I = 6 ; A = 400 + 6 ⇒ 406
