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)
A. 9. -7 + x = 9
A = 13.
b. -7 + 13 = -7 - 7 + 6.
a. 10. -10 + x = -2
A = 8
b. -10 + 8 = -2
