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

**Answer:**** Option B **

**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?

**Answer:**** Option E **

**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
