Question

find CI and A , when P= rs.72000, R= 6% , T= 3years​

Answer 1

☆ Solution ☆

Given :-

• Principal ( P ) = ₹ 72000
• Rate ( R ) = 6%
• Time ( T ) = 3 years

To Find :-

• Compound Interest ( CI )
• Amount ( A )

Step-by-Step-Explaination :-

We know that :-

Amount = P ( 1 + R/100 )^n

Putting the respective value,

Amount = 72000 ( 1 + 6/100 )³

Amount = 72000 ( 100 + 6/100 )³

Amount = 72000 ( 106/100 )³

Amount = 72000 × ( 106/100 × 106/100 × 106/100 )

Amount = 72000 × 106/100 × 106/100 × 106/100

Amount = 85753.152

Hence,

Amount = 85753.152

Now,

As we know that :-

Compound Interest = Amount - Principal

Putting the respective value,

Compound Interest = 85753.152 - 72000

Compound Interest = 13,753.152

Hence,

Compound Interest = 13,753.152

Answer 2

Answer:

☆ Solution ☆

Given :-

Principal ( P ) = ₹ 72000

Rate ( R ) = 6%

Time ( T ) = 3 years

To Find :-

Compound Interest ( CI )

Amount ( A )

Step-by-Step-Explaination :-

We know that :-

Amount = P ( 1 + R/100 )^n

Putting the respective value,

Amount = 72000 ( 1 + 6/100 )³

Amount = 72000 ( 100 + 6/100 )³

Amount = 72000 ( 106/100 )³

Amount = 72000 × ( 106/100 × 106/100 × 106/100 )

Amount = 72000 × 106/100 × 106/100 × 106/100

Amount = 85753.152

Hence,

Amount = 85753.152

Now,

As we know that :-

Compound Interest = Amount - Principal

Putting the respective value,

Compound Interest = 85753.152 - 72000

Compound Interest = 13,753.152

Hence,

Compound Interest = 13,753.152
