Question

Find simple interest if Principal= Rs.900 rate=6 %p.a
time=6 months.

Answer 1

Answer :-

• The simple interest is Rs. 27.

Step-by-step explanation:

To Find :-

• The simple Interest

Solution:

Given that,

• Principal = Rs. 900
• Rate = 6% p.a
• Time = 6 months

As we know that,

$\bigstar \: \: \sf{1 \: year \: = \: 12 \: months}$

So,

Converting 6 months to years,

$\sf{ = \dfrac{6}{12} \: year \: = \cancel{\dfrac{6}{12}}} \: year \: = \bf{\dfrac{1}{2} \: year}$

Now,

$\underline{\frak{As \: \: we \: \: know \: \: that,}}$

$\underline{ \boxed{\bf{Simple \: interest = \dfrac{P \times R \times T}{100}}}}$

Where,

• P = Principal
• R = Rate
• T = Time

$\sf{\therefore \: According \: the \: question}$

$\mapsto \: \sf{Simple \: interest = \dfrac{P \times R \times T}{100}} \\ \\ \\ \mapsto \: \sf{ \dfrac{900 \times 6 \times 0.5}{100}} \\ \\ \\ \mapsto \: \sf{ \dfrac{5600 \times 0.5}{100}} \\ \\ \\ \mapsto \: \sf{ \dfrac{2700}{100}} \\ \\ \\ \mapsto\sf{ \cancel{\dfrac{2700}{100}}} \\ \\ \\ \mapsto \: \boxed{\frak{ \purple{27}}} \: \star$

Hence,

• The simple interest is Rs. 27.

Answer 2

Answer:

Si 900

Time 6 yr

Rate 6 Percent

Si * 100

----------

time * Rate

900*100 - 90000

6*6-36

90000/36 - 2500
