Question

4,000 in 13 years at 2 paise per rupee
per month.

FIND INTREST AND AMOUNT​

Answer 1

Answer:

1. Interest = Rs 12480
2. Amount = Rs 16480

Step-by-step explanation:

Given that:

• Principal = Rs 4000
• Time = 13 years
• Rate = 2 paise per rupee per month

Converting 13 years into month:

• 1 year = 12 months
• 13 years = (12 × 13) = 156 months

Converting rate into percentage:

• Rate = 2/100 per month
• Rate = 2/100 × 100% per month
• Rate = 2% per month

We know that:

• SI = (P × R × T)/100
• A = P + SI

Where,

• SI = Simple interest
• P = Principal = 4000
• R = Rate = 2
• T = Time = 156
• A = Amount

Finding the interest:

⟶ SI = (4000 × 2 × 156)/100

⟶ SI = 1248000/100

⟶ SI = 12480

∴ Interest = Rs 12480

Finding the amount:

⟶ A = 4000 + 12480

⟶ A = 16480

∴ Amount = Rs 16480

Answer 2

Question:-

• 4,000 in 13 years at 2 paise per rupee per month.

To Find:-

• Find the interest and amount.

Solution:-

Given ,

• Principal = Rs 4000

• Time = 156 months

• Rate = 2% per month

First ,

We have to find the interest:-

$\dashrightarrow\sf \: Simple \: interest = \dfrac { PTR } { 100 }$

$\dashrightarrow\sf \: Simple \: interest = \dfrac { 4000 \times 156 \times \: 2 } { 100 }$

$\dashrightarrow\sf \: Simple \: interest = \cancel\dfrac { 1248000 } { 100 }$

$\dashrightarrow\sf \: Simple \: interest = 12480$

Now ,

We have to find the amount:-

$\dashrightarrow\sf \: Amount = 4000 + 12480$

$\dashrightarrow\sf \: Amount = 16480$

Hence ,

• Amount is Rs 16480
