28. The difference between simple interest and compound interest on a certain deposit for two years at 8 p.c.p. is Rs. 8. What is the amount of deposit

Explanation:

Given Intrest rate r = 8%
Deposited for year n = 2 years
Formula: SI = p*n*r/100
=> p*2*8/100 = 4p/25
CI = Amount - p
Amount = p(1 + r/100)^n
=> p(1 + 8/100)^2
CI = p(27/25)^2 - p
p(27/25)^2- p - 4p/25 = 8
p[27*27 - 625 - 100]/625 = 8
4p = 5000 => p = Rs. 1250

29. At a certain rate of simple interesrt,a sum double itsef in 10 years.In how many years would it treble itsef?

Explanation:

Lets Assume after 10 years amount = 2p
so, SI=2P-P = P
P=(P*R*10)/100
r=10%
now amount = 3P
SI= 3P-P=2P
2P=(P*10*T)/100
T=20years
