Question

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

Answer 1

Find the interest amount.

$I=1740-1200=540$

Use the formula for simple interest.

$I=prt/100$

Solve for t.

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

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

$540=180t$

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

$t=3$

3 years.

Answer 2

Answer
3 years
Step by step explanation
Interest = 1740 - 1200
= 540
SI = prt/100
540 = 1200*15*t/100
540 = 12*15*t
540 = 180*t
t = 540/180
t = 3 yrs
