Answer 1

$question$

A borrowed amount of ₹4000 amounts to ₹5400 in 5 years. How much will ₹5600 amount to, in 3 years at the same rate?

_______________________________________

$answer$

Principal= ₹4000

Amount= ₹5400

Interest= (A-P)

5400-4000

1400

_______________________________________

So the interest we obtained is ₹1400

_______________________________________

Now Time= 5years

Interest= P×R×T/100

1400= 4000×R×5/100= 200

Rate= 1400/200

______________________________________

Rate we get is 7%

$according \: to \: question$

How much will ₹5600 amount to, in 3 years at same rate.

Interest= P×R×T/100

5600×7×3/100

The interest we obtained is ₹1176

So now Amount= P+I

5600+1176

(Amount= ₹6776)
