Example 15 If Manohar pays an interest of Rs 750 for 2 years on a sum of Rs 4,500, find the rate of interest?I = Rs 750 T = 2 years P = Rs 4500 R = ? Now, I = ๐๐ ๐/100 750 = (๐๐๐๐ ร ๐น ร ๐)/๐๐๐ 750 = 45 ร 2R 45 ร 2R = 750 R = ๐๐๐/(๐๐ ร ๐) R = 375/45 R = 125/15 R = 25/3 R = 8 ๐/๐ % p.a So, rate of interest is 8 ๐/๐ % p.a
