Answer:
144 sweets
Step-by-step explanation:
Let
x----> number of sweets that Dan has
y----> number of sweets that Gordon has
z----> number of sweets that Malachy has
we know that
x=48
x/y=4/3----> y/x=3/4 ----> y=(3/4)x
Substitute the value of x
y=(3/4)48=36
x/z=4/5 ----> z/x=5/4 ----> z=(5/4)x
Substitute the value of x
z=(5/4)48=60
therefore
altogether there are x+y+z=48+36+60=144 sweets
