Question

in how many years will rupees 75000 amount to rupees 9000 at 4% percent p.a. simple interest​

Answer 1

Answer:

Here P=Rs.750

R=4% per annum

Amount=Rs.900

S.I=Amount−P

• =900−750
• =Rs.150

Simple interest=PRT/100

T= S.I*100/PR

=150*100/750*4

=5 yrs

Answer 2

$Interest = 9,000$

$Principal = 75,000$

$Interest = \frac{P×R×T}{100}$

$9,000 = 75,000 \times 4 \times \frac{t}{100}$

$9,000 = 3,000 \: t$

$t = \frac{9,000}{3,000}$

$t = \: 3 \: years \:$
