Question

principal= 150. Rate=5%. time=4years find the simple interest​

Answer 1

Answer:

$\huge \bf \: Given$

• Principal (P) = ₹150
• Rate (R) = 5%
• Time (T) = 4 years

$\huge \bf \: To \: find$

Simple interest

$\huge \bf \: Solution$

As we know that

$\huge \boxed { \sf \: SI= \frac{P \times R \times T}{100} }$

Putting values

$\sf \: SI \: = \dfrac{150 \times 5 \times 4}{100}$

$\sf \: SI \: = \dfrac{3 \times 5 \times 2}{1}$

$\sf \: SI\: = 30$

Answer 2

Given:

• Principal = ₹150
• Rate = 5%
• Time = 4 years

To find:

• Simple Interest = ?

Method:

$\rm{Simple\: Interest=\dfrac{Principal \times Rate \times Time}{100}}\\\\\\\\\implies \rm{S.I = \dfrac{150 \times 5 \times 4}{100}}\\\\\\\\\implies \rm{S.I = \dfrac{150 \times 20}{100}}\\\\\\\\\implies \rm{S.I=\dfrac{3000}{100}}\\\\\\\\\implies \boxed{\large{\bf{S.I= 30}}}$

Additional Information:

• There are 2 types of interest:

1. Simple Interest
2. Compound Interest

• For Simple Interest, use formula PTR ÷ 100
• For Compound interest, use the formula, Amount = P( 1 + R/100 )²ⁿ
