Question

Ankit wants to buy a car but it fell short of money by 50,000 he borrowed the money ​

Answer 1

Answer:

Step-by-step explanation:P= 50000

R=10%,,, T=3 yes

SI= prt/100

[50000×10×3] ÷ 100= 500×10×3=

15000= Interest

Therefore, amount to be paid = 50000+15000=65000 (in Rs)

plz give 5 stars :)

Answer 2

Answer:

Let the rate of interest =R%p.a.

In the first 3yrs,

principal =P=Rs7000, Time T=3yrs.

Then the interest =I

1

=

100

PRT

=

100

7000×R×3

=210R.

In the next (5-3)yrs=2yrs,

Pricipal =P=RS(7000−3000)=RS4000, Time =T=2yrs.

Then, the interest=I

2

=

100

PRT

=

100

4000×R×2

=80R.

∴ the total amount returned this time

=Rs(4000+I

1

+I

2

)=Rs5450

⟹4000+210R+80R=5450

⟹29R=1450

⟹R=5p.c.p.a.

So the rate of interest=5% p.a.
