Find the compound interest on rupees 7500 at 4%per annum for 2 years,compound annually. ​

Answer 1

✬ C.I = Rs 612 ✬

Step-by-step explanation:

Given:

• Principal is Rs 7500.
• Rate is 4% per annum.
• Time is 2 years.

To Find:

• What is the compound interest ?

Solution: Here we have,

• P = Rs 7500
• R = 4%
• T = 2 years
• C.I = ?

As we know that

★ Amount = P ( 1 + R/100)ⁿ ★

$\implies{\rm }$ 7500 ( 1 + 4/100)²

$\implies{\rm }$ 7500 ( 104/100 )²

$\implies{\rm }$ 7500 $\times$ (26/25)²

$\implies{\rm }$ 7500 $\times$ 676/625

$\implies{\rm }$ 5070000/625

$\implies{\rm }$ Rs 8112

So, Amount is Rs 8112

Now,

★ Amount = C.I + Principal ★

=> 8112 = C.I + 7500

=> 8112 – 7500 = C.I

=> Rs 612

Hence, Compound interest is Rs 612.

Answer 2

Step-by-step explanation:

⭐!! Question !!⭐

• Find the compound interest on rupees 7500 at 4%per annum for 2 years,compound annually.

⭐!! Given !!⭐

• P = 7500,
• r = 4
• n = 2

⭐!! To Find !!⭐

• Find the compound interest

⭐!! Solution !!⭐

We know CI = A - P

CI = P [ ( 1+r/100 )^n - 1 ]

CI = 7500[ ( 1 + 4/100 )^2 - 1 ]

CI = 7500 × ( 26/25 - 1 )( 26/25 + 1 )

CI = 7500[ ( 26/25 )^2 - 1 ]

CI = 7500 × 1/25 × 51/25

CI = 612

Hence the compound interest amount is Rs 612.

⭐!! Internal Information !!⭐

• A= amount
• P = principal
• R = rate of interest
• n = number of years
