Answer» Let the principal = PA/C to question, the simple interest on assume of money will be 225 after 3 years so, in 1 year simple interest will be 225/3 = 75rs. now, again question said " in the next 5 years principal becomes 3 times "e.g., S.I of 5 years + P = 3P S.I of 5 years = 2PS.I of 1 year × 5 = 2P75 × 5 = 2P 2P = 375 => P = 375/2 rs. now, total interest at the end of the 8 years = S.I of 1 years × 8 + P = 75 × 8 + 375/2 = 600 + 187.5 =787.5 rs. |
