a boy has a certain number of sweets. if he eats 16 a day they will last him 2 days longer than if he eats 18 a day. how many sweets has he ?
...
let him have x sweets
..
16 /day
number of days it lasts =x/16
..
if he eats 18/day
number of days = x/18
...
x/16 -x/18 = 2
...
LCD= 18*16
(18x-16x)/18*60=2
multiply by 18*60
18x-16x=2*18*16
2x=2*18*16
/2
x=16*18 =288 sweets
