|
Answer» Let the principal be Rs X. Then X × (1 + 10/100)3 – x = 331 => (x × 11/10 × 11/10 × 11/10 - x) = 331 => ((1331x-1000x)/1000) = 331 => 331x = 331000 => X = 1000 HENCE the principal is Rs 1000. Let the principal be Rs x. Then X × (1 + 10/100)3 – x = 331 => (x × 11/10 × 11/10 × 11/10 - x) = 331 => ((1331x-1000x)/1000) = 331 => 331x = 331000 => X = 1000 Hence the principal is Rs 1000. |
