Answer is 10: 5: 4

explanation-

Given :-

2A = 4B = 5C

To find :-

A:B:C

SOLUTION :-

Let

2A = 4B = 5C = x

So, 2A = x

A = $\dfrac{x}{2}$

Similarly ,

B = $\dfrac{x}{4}$

and

C = $\dfrac{x}{5}$

so, A: B: C = $\dfrac{x}{2}$ : $\dfrac{x}{4}$ : $\dfrac{x}{5}$

Lcm of 2,4,5 is 20

so A: B: C can be written equal to

$\dfrac{10x}{20}$ : $\dfrac{5x}{20}$ : $\dfrac{4x}{20}$

thus, A: B: C = 10: 5: 4
