Question
The H.C.F. of two numbers is 5 and their L.C.M. is 150. If one of the numbers is 25, then what is the number of the other?
A. 28
B. 26
C. 30
D. 32
Answer: C. 30
Solution:
H.C.F = 5
L.C.M = 150
One number = 25
Other number = H.C.F * L.C.M / One number
150*5/25
150 when reduced by 25 it is 6
So, 6*5 = 30
Other number is =30
