the sum when the number of years is equal to half of the rate percentage per annum. Find the simple interest (in. Rs) on rs 15,000 at the same rate as simple interest for 8 years.Solution
given - SI= P × 1/8, T= R×1/2 SI=PRT/100 P/8=P×R×R/200 R² =200/8=25 R² =25 R=5% now find the simple interest, P=1500 R=5% T=8years = (15000×5×8)/100 = 6000rs
