Question

a man borrowed rupees 700 from his friend he promised to return back the amount after six months at interest of 8% per annum how much money will he pay back after 6 months​

Answer 1

Answer:

728

Step-by-step explanation:

The formula for simple interest = P x R x N / 100

Therefore P=700

                 N=6 months

                 R=8%

SI=P x R x N /100

  = 700 x 1/2 x 8

           100        ( half because 6 months = half year)

 = 28

Therefore amount  = P + I

                                = 700+28

                                = 728

Therefore the man would pay 728 rupees to his friend

Answer 2

Question :

a man borrowed rupees 700 from his friend he promised to return back the amount after six months at interest of 8% per annum how much money will he pay back after 6 months

To find :

The amount he needs to pay after six months

Formula Used :

$\sf \small Interest = \frac{P×R×T}{100}$

$\sf \small Amount = Principal + Interest$

Given Data :

• Principal(P) → ₹ 700

• Rate(R) → 8 % p.a

• Time(T) → 6 months (1/2 year)

Solution :

$\sf \small Interest = \frac{P×R×T}{100}$

$\sf \small → \frac{700 \times 8 \times \frac{1}{2} }{100}$

$\sf \small→ \frac{700 \times 4}{100}$

$\sf \small Interest → 28$

We know that Amount = Principal + Interest

So,

Amount = 700 + 28 → ₹ 728

• Therefore he needs to pay ₹ 728 to his friend afer 6 months
