Question

the sum of total amount of money is distributed equally to some girl If there has been five girls less than each of them get Rs.45 more and if there are five girl more than each of them get Rs 15 less.Find how many girls are there​

Answer 1

Step-by-step explanation:

Let the sum of rupee be x

no of boys be y

then each boy get x/y

now if the no of boys increased by 10 each boy get x/(y+10) = (x/y)-1 => x/(y+10) = (x-y)/y .........(1)

now case 2nd if no of boys decrease by 15 each boy get x/(y-15)= (x/y) +3 => x/(y-15) = (x+3y)/y ...........(2)
