Question

find the amount to be pay after 4-1/2 years on a sum rs 650 at rate of 12.5%​

Answer 1

Answer:

Step-by-step explanation:

S.I =PRT/100                                  P=RS 650, R=12.5%,T=9/2 YEARS

    = 650×125×9÷1000×2

    = 365.7

AMOUNT= P+S.I

               = 650+365.7

                = 1015.7

Answer 2

Given:

• Principal = Rs. 650

• Rate = 12.5 %

• Time = 4 1/2 years = 4.5 years

What To Find:

We have to find -

• The amount.

Formulas Needed:

• SI = P × R × T ÷ 100
• A = P + SI

Abbreviations Used:

• P = Principal
• R = Rate
• T = Time
• SI = Simple Interest
• A = Amount

Solution:

• Finding the SI.

Using the formula,

⇒ SI = P × R × T ÷ 100

Substitute the values,

⇒ SI = 650 × 12.5 × 4.5 ÷ 100

Multiply 650, 12.5 and 4.5,

⇒ SI = 36,562.5 ÷ 100

Divide 36,562.5 by 100,

⇒ SI = Rs. 365.625

• Finding the A.

Using the formula,

⇒ A = P + SI

Substitute the values,

⇒ A = 650 + 365.625

Add the numbers,

⇒ A = Rs. 1,015.625

Final Answer:

∴ Thus, the amount is Rs. 1,015.625.
