Question

two numbers are in the ratio 3 : 4 if their LCM is 180 find the numbers

Answer 1

hello...

Let the 2 numbers be 3x and 4x

a×b = LCM × HCF 

3x × 4x = 180 × x 

12x² = 180x 

x = 180/12

x = 15 

a = 3x = 3×15 = 45

b = 4x = 4×15 = 60

HCF = x = 15 

Answer 2

Let Two numbers be 3x and 4x
LCM of 3x and 4x is 12x
Now 12x=180
x=15
3*15=45
4*15=60
