Simple interest is given by I = PTR/100. If P = ₹ 900, T =2 years;

1.	Simple interest is given by I = PTR/100. If P = ₹ 900, T =2 years; and R =5%, find the simple interest.
Answer» Given that the formula for simple interest (I) = \(\frac {PTR}{100}\) P = Rs.900, T = 2years, R = 5% ∴ The required simple interest (I) = \(\frac {PTR}{100}\) = \(\frac {900\times2\times5}{100}\) = 9 x 2 x 5 = Rs. 90

Answer»

Given that the formula for simple interest (I) = \(\frac {PTR}{100}\)

P = Rs.900, T = 2years, R = 5%

∴ The required simple interest (I) = \(\frac {PTR}{100}\) = \(\frac {900\times2\times5}{100}\)

= 9 x 2 x 5

= Rs. 90
