Interest returned on investing Rs. 12000 = 12000(1 + 15/100)2 – 12000 = 12000(115/100)2 – 12000 = 12000(23/20)2 – 12000 = 12000{232/202)- 1} = 12000{529/400)- 1} = 12000(529 - 400)/400 = Rs. 3870 So, interest returned on investing Rs. Y for 1 year at simple interest of 20% p.a. = 3870 + 20 = Rs. 3890 Or, Y × (20/100) = 3890 Or, Y = 3890 × (100/20) Or, Y = 19450
?% of 24% of 1200 + 12 × 11 = 204
