Question
Out of a total sum of ₹5,000, Danish invested one part
at 12% simple interest per annum and the remaining part at 10% simple interest per annum. If the total interest that accrued to Danish in two years equals ₹, 1044, what was the sum Danish invested at 12% simple interest per annum?Solution
Let Rs. P be invested at 12% simple interest. Hence, (5000 - P) is invested at 10% simple interest. According to the question, (P × 12 × 2)/100 + ((5000 - P) × 10 × 2)/100 = 1044 24P - 20P + 100000 = 104400 4P =4400 P=1100.
