LCM of two numbers is 189 and the numbers are in the ratio 9 : 7.
CONCEPT:
LCM: It is a number that is a multiple of two or more numbers.
CALCULATION:
Suppose the numbers are 9x and 7x.
⇒ LCM of 9x and 7x = 9 × 7 × x = 63x
According to the question,
63x = 189
⇒ x = 3
∴ Sum of the numbers = 9x + 7x = 16x = 48
