​

Answer 1

Question given :

Find the simple interest on Rs 3600 at 5 % per annum for 8 months.Also find the amount.

Given values :

• Rs. as Principal = ₹3600
• Rate of interest = 5%
• Time = 8 months = 8/12 yrs = ⅔ yrs.

To find :

• The Simple Interest
• And The amount

Solution :

$\sf {\orange {\underline {\pink{\underline{Simple\: Interest:}}}}}$

As we know that to find the SI we put the formula :

★$\tt\purple{SI=}\dfrac{PRT}{100}$

Putting the values,

$\tt\longmapsto{SI=}\dfrac{3600\times5 \times2}{100 \times3}$

$\tt\longmapsto{SI=12 \times5 \times2}$

$\tt\longmapsto{SI=60}\times{2}$

$\tt\longmapsto{SI=₹120}$

Thus,the Simple Interest $\tt{=Rs.120}$

$\sf {\orange {\underline {\pink{\underline{Amount:}}}}}$

★$\tt\purple{Amount=Principal+SI}$

$\tt\mapsto{Amount=3600+120}$

$\tt\mapsto{Amount=3720/-}$

Thus,

The Simple Interest $\frak{Rs.120}$

And the Amount $\frak{Rs.3720}$

Answer 2

Answer:

Simple Interest = Rs 3600 * 5% * 8 months / 100 = Rs 1440. Thus, the simple interest is Rs 1440. So, amount = Rs 3600 + Rs 1440 = Rs 5040
