If 30 , 50 , 96 , and y are in proportion, then the value of y is:

Correct option is D

Given:
If 30, 50, 96, and y are in proportion
Formula Used:
In proportion, a : b = c : d is equivalent to: a × d = b × c
Solution:
30 : 50 = 96 : y
=> 30 × y = 50 × 96
​$$\Rightarrow y = \frac{50 \times 96}{30} \\\Rightarrow y = \frac{4800}{30}$$​​
=> y = 160
