Rs 1,200 is borrowed at 12 % rate of interest p.a. borrowed for 3

years .find the amount to be paid at the end of the 3 year.​

Answer 1

Answer ツ

_____________________________________

(a) Principal = P = RS.1200

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

Time = T = 3 years

Simple interest = PTR/100

= 1200 × 3 × $\sf{\frac{12}{100}}$

= 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 = $\sf{\frac{PTR}{100}}$

= 7500 × 3 × $\sf{\frac{5}{100}}$

= RS.1125

Therefore, amount = Principal + Interest

= RS. 7500 + RS.1125

= RS.8625

Ans: The amount is RS.8625.

Answer 2

Answer:

(a) Principal = P = RS.1200

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

Time = T = 3 years

Simple interest = PTR/100

= 1200 × 3 ×10012

= 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 = 100 PTR

= 7500 × 3 × 1005

= RS.1125

Therefore, amount = Principal + Interest

= RS. 7500 + RS.1125

= RS.8625

Ans: The amount is RS.8625.
