The least number of complete years in which a sum of money put out at 20% compound interest will be more than doubled is:

A. 3

B. 4

C. 5

D. 6

4

P ( 1 + (20/100) )â¿ > 2P

=> (6/5)â¿ > 2

Now, [ (6/5) x (6/5) x (6/5) x (6/5) ]â¿ > 2

So, n = 4 years

There is 60% increase in an amount in 6 years at simple interest. What will be the compound interest of Rs. 12,000 after 3 years at the same rate?

A. Rs. 2972

B. Rs. 3120

C. Rs. 3972

D. Rs. 4120

Rs. 3972

Let P = Rs. 100. Then, S.I = Rs. 60 and T = 6 years

=> R = [ (100 x 60) / (100 x 6) ] = 10% p.a

Now, P = Rs. 12000. T = 3 years and R = 10% p.a

=> C.I = Rs. [ 1200 x { (1 + 10 / 100)³ - 1 } ]

=> C.I = Rs. [ 12000 x (331 / 1000) ]

=> C.I = Rs. 3972

The difference between simple and compound interests compounded annually on a certain sum of money for 2 years at 4% per annum is Re. 1. The sum (in Rs.) is:

A. 625

B. 630

C. 635

D. 640

625

Let the Principal be P, then

C.I = P x ( 1 + (4/100) )² - P = 51P/625

S.I = P x 4 x 2 / 100 = 2P/25

=> C.I - S.I = 1 = (51P/625) - (2P/25)

=> P = Rs. 625/-

A bank offers 5% compound interest calculated on half-yearly basis. A customer deposits Rs. 1600 each on 1st January and 1st July of a year. At the end of the year, the amount he would have gained by way of interest is:

A. Rs. 119

B. Rs. 120

C. Rs. 121

D. Rs. 122

Rs. 121

Amount = Rs. [ 1600 x ( 1 + 5 / (2 x 100) )² + 1600 x ( 1 + 5 / (2 x 100) )² ]

= Rs. [ 1600 x (41/40) x (41/40) + 1600 x (41/40) ]

= Rs. [ (1600 x 41 x 81) / (40 x 40) ]

= Rs. 3321

=> C.I = Rs. (3321 - 3200) = Rs. 121
