There are four equilateral triangles with sides 95 cm, 76 cm, 57 cm and 152 cm. What maximum size scale (in cm) can measure all of them exactly?
Given:
Four equilateral triangles with sides 95 cm, 76 cm, 57 cm, and 152 cm.
Formula Used:
Maximum size scale = HCF (Highest Common Factor) of the given lengths.
Solution:
95 = 5 × 19
76 = 2² × 19
57 = 3 × 19
152 = 2³ × 19
Therefore, HCF = 19

Deepesh has 168 litres of Oil A and 234 litres of Oil B. He fills a number of identical containers with the two types of oil in a manner that each container has only one type of oil, and all containers are completely filled. What can be the maximum volume (in litres) of each container that Deepesh uses, so that all the oil that Deepesh has, of both the types, can be poured into these containers?
