Question

If the ration of two positive numbers is 4:5 and their L.C.M is 140 then the number are 35,45
The comneund ratio of suhunlicate ratio and suh triplicate ratio of 7700​

Answer 1

Answer:

Ratio of two numbers =2:5

Let the numbers are 2x and 5x

Hcf (2x,5x)=x

Lcm(2x,5x)=140

Product of two numbers =lcm×hcf

2x*5x=140*x

x=(140*x)/(10*x)

x=14

Therefore

Required two numbers are

2x=2*14=28,

5x=5*14=70
