To calculate the amount you will earn on maturity, the formula is as follows: Amount = Principal X (1 + Interest Rate / compounding frequency) ^ (Term X Compounding frequency) In this case, it would be calculated as follows: Amount = ₹1 lakhs X (1 + 0.06/4) ^ (2 X 4) = ₹112,649 (rounded-off) The interest would then be calculated by subtracting the amount from the principal. Interest = ₹112,649 - ₹100,000 = ₹12,649 Thus, you would earn an interest of ₹12,649 in 2 years on your deposit of ₹1 lakh.
