Question
A sum of ₹8,500 amounts to ₹11,900 in 5 years at
simple interest per annum. If the rate of interest is increased by 3%, then the increased amount for the same period isSolution
Now, according to the question SI = A-P SI=Rs. (11900 - 8500) = Rs 3400 SI = (PRT) / 100 Rs 3400 = (8500×R× 5) / 100 R = (680/85) R = 8% Now, the rate of interest is increased by 2% = (8 + 2) % = 10% SI=Rs. (8500 ×10 × 5) / 100 SI = Rs.4250 Now A =P+SI =8500+4250 =12750.
