Answer 1

Answer:

Interest Paid on a Certain sum after 4 years at 7% = 560 × 4 = Rs. 2240

Principle = Rs. 8000

Step-by-step explanation:

Hey Mate,

Given,

Interest per year = Rs 560

Rate = 7%

So,

S.I = P × R × T /100    #{ S.I = Simple Interest , P = Principle , R = Rate }

560 = (P × 7 × 1) / 100

P = (560 × 100) / 7

P = 8000.

Interest Paid on a Certain sum after 4 years at 7% = 560 × 4 = Rs. 2240

Answer 2

a/c to question,
interest rate 7% per annum.
also interest are paid 560 Rs every year.

so, total interest are paid in four years = 4 years × 560 Rs/year
= 2240 Rs.

now let P be the principal or sum.

here, S.I = 2240 Rs , r = 7% /annum , t = 4 yrs

use formula, S.I = P × r × t/100

2240 = P × 7 × 4/100

P = 2240 × 100/(7 × 4)

P = 8,000 Rs.

hence, the sum is 8000Rs.
