Question

Calculate S.I. on Rs. 5000 for 18 months 5% p.a.​

Answer 1

Answer:

The simple interest is of Rs. 375.

Step-by-step explanation:

Given :

Principal = Rs. 5000

Time = 18 months

Rate = 5%

To find :

The Simple Interest

Solution :

First, convert the 18 months into years,

⇒ 18/12

⇒ 1.5 years

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

⇒ SI = (5000 × 5 × 1.5)/100

⇒ SI = 5000 × 7.5/100

⇒ SI = 50 × 7.5

⇒ SI = 375

Simple interest = Rs. 375

Therefore, the simple interest is of Rs. 375.

Answer 2

♀Question :-

• Calculate S.I. on Rs. 5000 for 18 months 5% p.a.

♀Solution :-

Given :

• Principal (P) = Rs 5000
• Rate (R) = 5%
• Time (T) = 18 months

To Find :

• Simple Interest (SI) .

Now,

• Time= $\dfrac{18}{12} \:years = \dfrac{3}{2}\: years$

$\boxed{\tt{SI=\dfrac{P\times R\times T}{100}}}$

$\implies {\sf {SI=\dfrac{P\times R\times T}{100}}} \\ \\ \implies {\sf {SI = Rs \: (\dfrac{5000 \times 5 \times \dfrac{3}{2} }{100} )}}\\ \\ \implies {\sf {SI=Rs \: (\frac{37500}{100})}} \\ \\ \implies {\sf {SI = Rs \: 375}}$

∴ SI = Rs 375
