1.	The difference of compound interest and simple interest for rupees 2000 and 12% for 1 year is rupees?please reply soon it's very much urgent option is 1,0,12,20
Answer» GIVEN:- P = Rs.2000 R = 12 % T = 1 year To find:- $\sf{\underline{Difference\:between\:Simple\:Interest\:and\:Compound\:Interest}}$ Solution:- 1st case, We know, $\sf{<klux>SI</klux> = \dfrac{P\times R\times T}{100}}$ = $\sf{SI = \dfrac{2000\times12\times1}{100}}$ = $\sf{SI = Rs.240}$ Now, 2nd case, We know, $\sf{A = P\bigg(1+\dfrac{r}{100}\bigg)^t}$ = $\sf{A = 2000\bigg(1+\dfrac{12}{100}\bigg)^1}$ = $\sf{A = 2000\bigg(\dfrac{100+12}{100}\bigg)^1}$ = $\sf{A = 2000\bigg(\dfrac{112}{100}\bigg)^1}$ = $\sf{A = 2000\times\dfrac{112}{100}}$ = $\sf{A = Rs.2240}$ Difference between SI and CI:- $\sf{Difference = CI - SI = Rs.(2240 - 240) = Rs. 2000}$ Note:- SI = Simple Interest CI = Compound Interest R = Rate T = Time A = AMOUNT
