In how many years will Rs.1200 at the rate of 15% interest amount to Rs. 1740

Anvisha [2.4K]

Find the interest amount.

$I=1740-1200=540$

Use the formula for simple interest.

$I=prt/100$

Solve for t.

$540=1200 \times 15\% \times t$

$540=1200 \times \frac{15}{100} \times t$

$540=180t$

$t=\frac{540}{180}$

$t=3$
