Question

find the time when the principal is rupees 5000 rate 30.5 per annum and interest is peace 1050

Answer 1

Hey...!!!

Principal = Rs 5000
Rate of interest per annum = 30.5%
S.I = Rs 1050

Time = S.I x 100 / P x R
= 1050 x 100/ 5000 x 30.5
= 0.68

So, time = 0.68 years

Hope it helps...!!!

Answer 2

$i = \frac{prt}{100} \\ 1050 = \frac{5000 \times 30.5 \times t}{100} \\ t = \frac{1050 \times 100}{5000 \times 30.5} = \frac{1050}{5 \times 305} \\ = \frac{210}{305} = \frac{42}{61} years$
