Question

v) ₹3,200 ; R = 25% p.a. ; n = 3 years find the compound interest
​

Answer 1

Answer:

The CI is Rs. 3050

Step-by-step explanation:

Formula-  

• Amount  = Principal × $(1 + \frac{Interest}{100} )^{Time}$
• CI = Amount - Principal

Given,

1. Principal = Rs. 3,200
2. Interest = 25%
3. Time = 3 years

Insert values,

• Amount = Rs. 3200 x $(1 + \frac{25}{100} )^{3}$
• Amount = Rs. 3200 x ( $\frac{125}{100}$ )$^{3}$
• Amount = Rs. 3200 x $\frac{5}{4} . \frac{5}{4} . \frac{5}{4}$
• Amount = Rs. 50 x 125 = Rs. 6,250

Find CI,

• (Rs. 6,250 - Rs. 3,200) = CI
• Rs. 3, 050 = CI
