Question

If 4000 amount of 5000 in 2 years,find the rate of simple interest per annum.​

Answer 1

$\sf \underline{Answer}$

Given:-

• Principal = 4000
• Time = 2 years
• Amount = 5000
• Interest = Amount - Principal = 1000
• Rate = ?

_____________________________

We use the formula of simple interest,

$\sf \: interest = \frac{principal \times rate \times time}{100}$

$\sf \: 1000 = \frac{4000 \times rate \times 2}{100}$

$\sf \: rate = \frac{100}{4 \times 2}$

$\sf \: rate = 12.5\%$

Answer 2

Answer:

12.5%

Step-by-step explanation:

• Principle- ₹4000
• Amount- ₹5000
• Time- 2 years
• Rate- R(say)

• Interest- Amount-Principle

= ₹5000-4000

• Simple interest= ₹1000
• Interest:
• $\frac{principle \times rate \times time}{100}$1000= 4000×R×2/100
• R= 1000×100/4000×2
• After simplifying this
• we get 2/25
• Then divide it,
• we get 12.5%
