This is a commonly seen word problem for PSLE. When handling this concept, it is important to note that quantity of items does not equal to the value of items.

To solve the work problem above, first determine how many bottles are there in one group. To do that, you need to identity 6 as a common multiple of 2 and 3 [P4 concept].

1 group: 6 small bottles -> $20

6 big bottles -> $45

Difference for 1 group ->

$45 - $20 = $25

Number of groups -> $100 ÷ $25 = 4

Number of bottles-> 4 × 12 = 48
