Question

find the amount of principal = rs 1200 at 12% p. a​

Answer 1

Answer:

The amount is RS.8625.

Step-by-step explanation:

(a)

Principal = P = RS.1200

Rate of interest = R = 12% p.a.

Time = T = 3 years

Simple interest = PTR/100

= 1200 × 3 × 12/100

= RS.432

Therefore, amount = Principal + Interest

= RS.1200 + RS.432

= RS.1632

Ans: The amount is RS. 1632.

(b)

Principal = P = RS. 7500

Time = T = 3 years

Rate of interest = R = 5% p.a.

Simple interest = PTR/100

= 7500 × 3 × 5/100

= RS.1125

Therefore, amount = Principal + Interest

= RS. 7500 + RS.1125

= RS.8625

Ans: The amount is RS.8625.
