${\pink{\huge{Rupees\: 1290}}}$

⭐${\blue{\huge{Explanation}}}$⭐

✔✅Simply use the formula to calculate the compound amount and subtract principle frkm it to get the compound interest✅✔

Formula to claculate compund amount:

Formula to claculate compund amount:CA = P[1+R/100]ⁿ

Where p is principle amount, r is rate of interest and n is the time

Put the values and get CA

CA = 4000 [1+15/100]²

CA = 4000 [1+3/20]²

CA = 4000 [23/20]²

CA = 4000 × 23/20 × 23/20

CA = 5290

Compund interest = CA - P = 5290 – 4000 = 1290
