Question

uma invested 10,000 at 5% per annum for 10 years find the amount she will receive after 10 years.​

Answer 1

Given:

• Principal = Rs. 10000
• Rate = 5%
• Time = 10 years

What To Find:

We have to find the amount.

How To Find:

To find the amount, we have to use,

• $\sf{SI = \dfrac{P \times R \times T}{100}}$
• A = P + SI

Solution:

• Finding the simple interest.

Using the formula,

⇒ $\sf{SI = \dfrac{P \times R \times T}{100}}$

Substitute the values,

⇒ $\sf{SI = \dfrac{10000 \times 5 \times 10}{100}}$

Cancel the zeros in 100 and 10000,

⇒ $\sf{SI = \dfrac{100 \! \! \! \not 0 \! \! \! \not 0 \times 5 \times 10}{1 \! \! \! \not 0 \! \! \! \not 0}}$

Also written as,

⇒ SI = 100 × 5 × 10

Multiply the numbers,

⇒ SI = Rs. 5000

• Finding the amount.

Using the formula,

⇒ A = P + SI

Substitute the values,

⇒ A = Rs. 10000 + Rs. 5000

Add the amount,

⇒ A = Rs. 15000

∴ Thus, Uma will receive Rs. 15000 as an amount after 10 years.
