Answer 1

Answer:

Principal = 3000 rs.

Rate = 7%

Time = 1 year

S.I. = P * R * T

             100

S.I. = 3000 * 7 * 1

                100

S.I. = 210 rs.

Amount = S.I. + Principal

              = 210 + 3000

              = 3210 rs.

Answer 2

Concept:

Simple interest = ( principal × rate × time ) ÷ 100

Given:

We are given that:

Principal = Rs.3000

Interest = 7 %

Time = 1 year

Find:

Simple interest and amount at the end of 1 year.

Step-by-step explanation:

Principal amount = P = Rs.3000

Interest rate = R = 7 %

Time period = T = 1

Simple Interest = PRT / 100

SI = ( 3000 × 7 × 1 ) / 100

SI = Rs.210

Amount (A) = P + SI

A = 3000 + 210

A = Rs.3210.

Therefore, the amount is Rs.3210 and the simple interest is Rs.210.
