Rohit invested ₹50, 000. It offers an annual interest of 10% for a period of five years. The interest for the initial year with compound interest will be 50,000 x 10/100 that will give you ₹5000. Similarly, the interest for Rohit’s second year will be formulated in the same manner. It will be calculated on the accumulated amount which is 50,000 + 5000= 55,000

Here, the interest for the 3rd year will be calculated in this manner:
50,000 + 5,000+ 5, 550 = 60,550 x 10/100 = ₹6055

Similarly, following the same calculation, the interest for the fourth year for Rohit’s initial investment will be calculated in this manner:
50,000 + 5, 000 + 5, 500 + 6055= ₹66, 605 x 10/100= 6,660.5
Moving on to the 5th year, the final interest will be calculated in the following manner: 50,000 + 5,000 + 5,550 + 6055 + 6,660.5 = ₹73265.5 x 10/100 = ₹ 7,326.55
