Answer 1

Answer:

Amount received is Rs. 5280.

Step-by-step explanation:

Given :

Sum of money = Rs. 4000

For = 2 years

Rate = 16 %

To find :

The Amount

Solution :

• P = 4000
• R = 16
• T = 2

$\boxed{\tt{SI = \frac{Principal \times Rate \times Time}{100}}}$

⇒ SI = (4000 × 16 × 2)/100

⇒ SI = (40 × 16 × 2)

⇒ SI = 640 × 2

⇒ SI = 1280

Simple Interest = Rs. 1280

$\rule{300}{1.5}$

$\boxed{\tt{Amount = Principal + Simple \: Interest}}$

⇒ Amount = 4000 + 1280

⇒ Amount = 5280

Therefore, amount received is Rs. 5280.

QUESTION :

Find the amoubt on rs 4000 for 2 year at 16% per annum

SOLUTION :

Formulae Used : C . I. Formula ..

$\sf{ A = P { \dfrac{(1 + R) }{100} } ^ n }$

Substituting the values :

$\sf{ A = 4000 {{ (\dfrac{117}{100}})}^2 }$

${\sf{\leadsto{ A = 4000 \times \dfrac{117}{100} \times \dfrac{117}{100} }}}$

${\sf{\mapsto{ A =Rs. \: 5475.6}}}$
