Question

principal rs 2000; rate of interest = 10 p.c.p.a no of years 2 find the interest​

Answer 1

$\frac{p \times r \times t}{100}$

$\frac{20 \cancel{00} \times 10 \times 2}{ \cancel{100} }$

$20 \times 10 \times 2 = 400$

$interest = 400rs$

Answer 2

$si = \frac{p \times r \times t}{100}$

$si = \frac{2000 \times 10 \times 2}{100}$

$si = 20 \times 10 \times 2$

$si = 400$
