Question
HCF of two numbers 75 and 105 can be expressed in the
form of (15m – 120) whereas LCM of these two numbers can be expressed in the form of (50n – 25). Find the ratio of (n × m).Solution
HCF of 75 and 105 = 15 LCM of 75 and 105 = 525 According to the question, => 15m – 120 = 15 => m = 9 And, 50n – 25 = 525 => n = 11 Required answer = n x m = 99
