Options:
A .  25
B .  50
C .  45
D .  75
Answer: Option B
:
B
Given: L.C.M. (100,150) = 300
We know that product of two numbers is equal to the product of their HCF and LCM.
Product of numbers 100and 150 = HCF × LCM
100×150 = HCF × 300
HCF = 100×150300
HCF = 15000300
HCF = 50
HCF of 100 and 150 is 50.
