Question

plz help me plzzzzzz

Answer 1

Answer: 541

Step-by-step explanation:

first take time as 2 instead of 2.5

and we can take

A = P( 1 + r /100)^n  Where  A = Amount  and n = number of years so

A= 2000(1+10/100)^2

10/100 will become 1/10

and we take LCM

A=2000((10+1)/10)^2

A=2000(11/10)^2

A= 2000 * 11/10 * 11/10           divide it and we will get

A= 2420

Now take P = 2420

and the simple Interest of the 1/2 years = PRT/100

= (2420*10*1/2)/100

=121

so amount after 2.5 years  = 2420 + 121

= 2541

and Compound Interest = Amount - Principal

                                     = 2541-2000

                                     = 541 rupees
