Question

find the principal amount (a) r= 2.5%, n=2 years, I=₹100

Answer 1

$i = \frac{p \times r \times n}{100} \\ 100 = \frac{p \times 2.5 \times 2}{100} \\ 100 = \frac{5p}{100} \\ 5p = 100 \times 100 \\ p = \frac{100 \times 100}{5} \\ p = 2000 \\ principle \: amount \: is \: 2000 \: rs \: \\ mark \:as \: brainliest..$
