उत्तर
For 1st year :
P = Rs. 48,000; R = 10 % and T = 1 year
Interest = Rs. `[48,000 xx 10 xx 1]/[100]` = Rs. 4,800
Amount = Rs. 48,000 + Rs. 4,800 = Rs. 52,800
For 2nd year :
P = Rs. 52,800; R = 10 % and T = 1 year
Interest = Rs. `[52,800 xx 10 xx 1]/[100]`= Rs. 5,280
Amount = Rs. 52,800 + Rs. 5,280 = Rs. 58,080
For 3rd year :
P = Rs. 58,080; R = 10% and T = 1 year
Interest = Rs.`[58,080 xx 10 xx 1]/[100]` = Rs. 5,808
