Question

The simple interest on Rs.625 at 6 1/2prcent per annum for 2 1/2 years is

Answer 1

Step-by-step explanation:

Given: Principal, P = Rs 625

Rate, R = 1/2%

Time, T = 2 1/2 years = 5/2 years

To find: Simple Interest

Solution: Using the formula,

$si = \frac{prt}{100}$

where, SI is interest, P is principal, R is rate and T is time

Placing the values,

$si = \frac{625 \times 1 \times 5}{100 \times 2 \times 2}$

[ multiplying 2 and 2 and 100 ]

$si = \frac{625 \times 5}{400}$

[ dividing 5 and 400, we get 80 ]

$si = \frac{ \cancel{625}}{ \cancel{80}}$

[ dividing 80 and 625, we get 125/16 ]

$si = \frac{125}{16}$

[ dividing 125 and 16, we get 7.81 ]

Therefore, Interest = Rs 7.81
