Question

find the compound interest on principal is 6655 time is 3years and rate is 10 p .c.p.a​

Answer 1

Now, in the question we are provided with A = Rs 6,655 ,R = 10% and Time period, T = 3 years. Therefore, the Principal at which the amount becomes Rs 6,655 in 3 years, compounded annually at the rate of 10% p.a. is Rs 5,000.

Answer 2

Answer:

2202.805

Explanation:

For the first year, always the simple interest and compound interest is same so, SI of 6655 is 665.5 ( as interest is 10percent of sum)

For the second year, in compound interest, the interest is compounded annually so

The new amount is 6655+665.5 = 7320.5

The interest for second year =10 percent of 7320.5 = 732.05

For the third year, the new amount =7320.5+732.05= 8052.55

The interest for third year = 10 percent of 8052.55

Finally, the overall interest for three years =665.5+732.05+805.255 =2202.805

Alternative method :

Refer the above photo, then substitute the values given in the question and will get the final sum as 8857.805

Now subtract the initial sum from the final sum, you will get the interest

Interest = 8857.805 - 6655 =2202.805

Hope you got it
