A certain sum of money amounts to Rs 15900 at simple rate of interest at 6 percent per annum in 5 yr.What is the value of principal sum?​

Answer 1

Answer:

p = 12230.77

Step-by-step explanation:

let, principal = p

Formula :

$p + \frac{p \times r \times t}{100} = amount \\ or \: p + \frac{p \times 6 \times 5}{100} = 15900 \\ or \: 100p + 30p = 1590000 \\ or \: 130p = 1590000 \\ or \: p = \frac{1590000}{130} = 12230.77$
