Answer 2

Answer:

• Amount to be paid by Sanika if there is simple interest = Rs 15600

• Amount to be paid by Sanika if there is compound interest = Rs 15972

Step-by-step explanation:

Given that:  

• Time = 3 years
• Principal = Rs 12000
• Rate of interest = 10% per annum

To Find:  

• Amount to be paid by Sanika if there is simple interest.

• Amount to be paid by Sanika if there is compound interest.

Formula used:  

Amount in simple interest:  

• A = P + (P × R × T)/100

Amount in compound interest:  

• A = P(1 + R/100)ᵀ

Where,  

• P = Principal
• R = Rate of interest
• T = Time
• A = Amount

Finding amount if there is simple interest:

⟶ A = 12000 + (12000 × 10 × 3)/100

⟶ A = 12000 + 3600

⟶ A = 15600

∴ Amount in simple interest = Rs 15600

Finding amount if there is compound interest:

⟶ A = 12000(1 + 10/100)³

⟶ A = 12000(1 + 0.1)³

⟶ A = 12000(1.1)³

⟶ A = 12000 × 1.1 × 1.1 × 1.1

⟶ A = 15972

∴ Amount in compound interest = Rs 15972
