Let us take pumpkins as p, ladybugs as b and starfish as s.

3p= 12

1p=4

b+b+p=34

2b=34-p=34-4=30

1b=15

b+b+s=39

s=39-(b+b)=9

So, p= 4, b= 15, s= 9

Let us take papaya as p, apple as a and clock as c.

p+p+a =38

p+p+a+a=68

There is an extra a, so:

a=68-38=30

2p=38-30=8

p=4

p+p+c=9

c=9-(p+p)=9-(4+4)=1

So, a= 30, p= 4,c= 1
