Question

Roshanara deposited a certain amount with a leasing company at the rate of interest of 20% compounded annually. At the end of 3 years, he received back
21,600. Find the amount deposited.​

Answer 1

Answer:

Rs. 12,500

Step-by-step explanation:

Let the amount deposited be x.

Therefore,

According to question

x(1+R/100)³ = 21,600

=> x = 21600× 100³/(100+20)³

=> x = 21600 × 100³/120³ = 21600 × 10⁶/12³×10³

=> x = 21600 × 10³/12³ = 21600 ×1000/1728 = Rs. 12,500

Therefore,

Amount he deposited in = Rs .12500
