Question

patil borrowed some money for 4 years atsimple interest the rate of interest 8% if he return 13,200 althogether at the end of 4 years. how much had he borrowed?​

Answer 1

let principle =x

$amount = principle + \frac{principle \times rate \times time}{100}$

13200=x+(x*8*4)/100

let we take common 'x'

13200=x[1+(1*8*4)/100]

13200=x[1+(32)/100]

13200=x[100+32]/100

13200=x(132)/100

x=13200*(100)/132

x=10000
