each of pencil pack is of 24
and
each of crayon pack is of 32
so pencils are multiple of 24
and
crayons are multiple of 32
but both must be same
it means we have to take their l.c.m.
24 = 2 × 2 × 2 × 3
32 = 2 × 2 × 2 × 2 × 2
lcm = 2 × 2 × 2 × 2 × 2 × 3
lcm = 96
so we can buy 96 of each pencils and crayons
I.e. 24 × 4 packs of pencils
and 32 × 3 packs of crayons
