Question

what sum will yield an interest of 800 rupees for 2 years at the rate of 4% per annum ​

Answer 1

I = P×R×T/100

therefore,

$800 = p \times 4 \times 2 \div 100$

hence

P= 8000/8

P= 1000

Answer 2

Answer:

p= 10000

Given:-

• principle =?
• interest = 800
• time = 2
• rate = 4%

To find:-

• principle

Solution:-

here,

we will simple intest formula

$s.i = \frac{p \times t\times r}{100} \\ \\ 800 = \frac{p \times 2 \times 4}{100} \\ \\ p = \frac{800 \times 100}{8} \\ \\ p = 100 \times 100 \\ \\ p = 10000$
