Question

if rupees 1250 amount to rupees 1550 in 3 years at simple interest what will rupees 3200 amount to in 4 years at the same rate ?​

Answer 1

Answer:

Step-by-step explanation:

principal amount=1250

time=3 years

rate of interest=r%

total amount=1550

simple interest=1550-1250=300

 using the formula:-

    300=1250*3*r/100

    300=375r/10

    r=3000/375=8%

new principal=3000

time=4 years

rate of interest=8%

simple interest=3000*4*8/100=960

total amount=960+3000=3960

Given

• principal=1250
• amount=1550
• time=3years

simple interest=A-P

=1550-1250

=₹300

by using formula to find rate

$r= \frac{si \times 100}{p \times t} \\ \\ r = \frac{300 \times 100}{1250 \times 3} =>r = 8\%$

Than if

• principal=3200
• rate=8%
• time=4years
• amount=?

using formula to calculate si

$si = \frac{3200 \times 4 \times 8}{100} =>si = 1024$

hence:-

• amount=3200+1024
• =₹4224
