6) Steve's Height = 8/3 x 45
= 120 cm
Luke's Height = 4/3 x 120
= 160 cm
Difference in Height = 160 -
120 cm = 40 cm
7) Multiple of 12 = 12,24,36,48,60,72,84,96
From the list, there can be either 96 or 84 pens.
1st case:
Pens = 96
Pencils = 48
Erasers = 56
2nd case:
Pens = 84
Pencils = 42
Erasers = 74
So, number of erasers is 56 or 74 since one of these values fulfills the condition of the qn.
