Question

3. The ratio between two numbers is 3:4 and their
LCM is 180. The first number is:
(a) 60
(b) 45
(c) is
(d) 20

The numbers would be 3x and 4x
and their LCM will be 12x
so 180/12 is 15
so our first no. will be 3x = 3×15 = 45

therefore option b is correct​

Answer 1

Answer:

let the no be x

their lcm is 12x

1st no equal 3x/12x×180 =45

2nd no = 4x/12x×180=60

therefore 1st no is 45

option "b"is correct option
