Answer 1

given:

Rate of interest =42%

Time=5 years

Interest amount=24000

To Find: principal amount

solution:

simple interest formula is  s=(p * r * t)/100;

so ,putting the value

=> interest amount +p=(p* 42 *5)/100

=>24000+p=210p/100

=>24000= (21p/10)-p

=>24000=11p/10

=>p=(24000 * 10)/11

=>p=21818.18

so the principal amount is 21818.18
