Answer:

Ok answer is below

Step-by-step explanation:

Given:

Simple interest = Rs. 2300, the rate = 20% and time = 2 years

Formula used:

If P = Principal, R = Rate of Interest, and T = Time Period; then:

Simple interest (S.I) = (P × R × T)/100, and

Compound interest (C.I) =  P[(1 + R/100)2 - 1]

Calculation:

According to question,

Simple interest (S.I) = (P × R × T)/100

2300 = (P × 20 × 2)/100

⇒ P = 5750

Now, (C.I) =  P[{(1 + (R/100)}t - 1]

⇒  5750[{(1 + (10/100)}2 - 1]

⇒ 5750 × [{(11/10) × (11/10)} - 1] 

⇒ 5750 × (21/100) = 1207.5

∴ Compound interest is Rs. 1207.5.
