and
Step-by-step explanation:
Given: In ΔMNO and ΔQRS

To prove that the triangles are similar by the SSS similarity theorem [corresponding sides of similar triangles are proportional], there must be the third pair of corresponding sides,
That must be
and
such that 
Number of containers for 2 litres of water = 1
So, number of containers for 1 litre of water = ½
So, number of containers for 30 litres of water

= 15
So, 15 of these containers would be needed to fill a 30-liter drum.
1,5,8 would be the correct answer
