Question

the ratio of two numbers is 3:4 and their LCM is 48. The sum of the two number is ????

Answer 1

first know what is LCM

it is least common multiple or a number that can be fairly divided by each of the numbers taken initially.

so let us suppose the common multiple to be X

Now as per your question,

2X*3X = 48

6X = 48

X = 48/6

X = 8

so the numbers are 16 and 24

Answer 2

The two nos. are 12 and 16.Therefore the sum of the nos. is 12+16=28 . Hope this answer helps you !!
