A Sum Of Rs.4800 Is Invested At A Compound Interest For Three Years,

1.	A Sum Of Rs.4800 Is Invested At A Compound Interest For Three Years, The Rate Of Interest Being 10% P.a., 20% P.a. And 25% P.a. For The 1st, 2nd And The 3rd Years Respectively. Find The Interest Received At The End Of The Three Years?
Answer» Let A be the amount received at the end of the THREE years. A = 4800[1 + 10/100][1 + 20/100][1 + 25/100] A = (4800 * 11 * 6 * 5)/(10 * 5 * 4) A = Rs.7920 So the interest = 7920 - 4800 = Rs.3120 Let A be the amount received at the end of the three years. A = 4800[1 + 10/100][1 + 20/100][1 + 25/100] A = (4800 * 11 * 6 * 5)/(10 * 5 * 4) A = Rs.7920 So the interest = 7920 - 4800 = Rs.3120

Answer»

Let A be the amount received at the end of the THREE years.

A = 4800[1 + 10/100][1 + 20/100][1 + 25/100]

A = (4800 * 11 * 6 * 5)/(10 * 5 * 4)

A = Rs.7920

So the interest = 7920 - 4800 = Rs.3120

Let A be the amount received at the end of the three years.

A = 4800[1 + 10/100][1 + 20/100][1 + 25/100]

A = (4800 * 11 * 6 * 5)/(10 * 5 * 4)

A = Rs.7920

So the interest = 7920 - 4800 = Rs.3120
