If $$\frac{1}{a}:\frac{1}{b}:\frac{1}{c} = 2:3:5$$​, then a:b:c is equal to:

Correct option is C

Given:

​$$\frac{1}{a}:\frac{1}{b}:\frac{1}{c} = 2:3:5$$​​

Formula Used:

Ratio and Proportions

Solution:

If $$\frac{1}{a}:\frac{1}{b}:\frac{1}{c} = 2:3:5$$​ 

Then $$a : b:c = \frac{1}{2}:\frac{1}{3}:\frac{1}{5}$$​​

LCM of (2,3,5) = 30

a : b:c =$$\frac{1}{2}\times 30:\frac{1}{3} \times 30 :\frac{1}{5} \times 30$$​​

a : b:c = 15:10:6
