Let the Principal = Rs 100

Rate of interest = 10% per annum compounded annually

Period = 2 years = 2 compounding period

Princupal of Rs 100 will amount to in 2 years at 10% per annum compounded annually to A, where A

A = 100 [ 1 + (10/100)]² = 100 × (110/100)² = 100 × (11/10)² = Rs 121

C I on Rs 100 in 2 years at 10% per annum = Rs 21

If C I is Rs 378 in 2 years the Principal = (378 × 100)/21 = Rs 1800

Simple interest on Rs 1800 in 2 years And 10
