Three numbers are in the ratio 5/20 : 8/16 : 8/14. The difference between the largest and the smallest number is 54.
Find the largest number.

Correct option is D

Given: ​

​$$\frac5{20} : \frac8{16} : \frac{8}{14}$$

Largest - Smallest number = 54 

Solution: ​

​$$\frac5{20} : \frac8{16} : \frac{8}{14}$$ can be written as

= 7 : 14 : 16 

Now 

16 - 7 unit = 54 

9 unit = 54 

1 unit = 6 

Largest number = $$16\times 6 = 96$$​​
