Question

Calculate the interest for each of the following cases. (a) P= 600, n = 4 years , r = 4 %. solution ​

Answer 1

Answer:

P= 600, n = 4 years , r = 4 %.

Simple interest = PRN/t

• = 600*4*4/100
• =9600/100
• =96

Answer 2

Question :-

● Calculate the Interest :-

• Principal = Rs. 600
• Rate of Interest = 4 %
• Time Period = 4 years .

⠀⠀⠀⠀⠀⠀⠀

Answer :-

• Simple Interest is Rs. 96

⠀⠀⠀⠀⠀⠀⠀

Explanation :-

• Here, Principal is given Rs. 600 . Rate of Interest is 4 % . Time Period is 4 years . And, we have to calculate the Simple Interest .

⠀⠀⠀⠀⠀⠀⠀

● Formula Required :-

• $\sf { Simple \: Interest = \frac{P \times R \times T}{100} }$

⠀⠀⠀⠀⠀⠀⠀

∴ By substituting the given values :-

⠀⠀⠀⠀⠀⠀⠀

$\Longrightarrow \: \sf{Simple \: Interest = \frac{600 \times 4 \times 4}{100} }$

$\Longrightarrow \: \sf{Simple \: Interest = \frac{6 \times 4 \times 4}{1} }$

$\Longrightarrow \: \sf{Simple \: Interest = 6 \times 4 \times 4}$

$\Longrightarrow \: \sf{Simple \: Interest = Rs. \: 96}$

⠀⠀⠀⠀⠀⠀⠀

Hence :-

• Simple Interest = Rs. 96
