If 18 , 36 , 14 , and y are in proportion, then the value of y is:

Correct option is C

Given:

Four numbers are in proportion: 18, 36, 14, and y

Formula Used:

a : b = c : d

=> a × d = b × c

Solution:

18 : 36 = 14 : y

​$$18 \times y = 36 \times 14$$​​

18y = 504

y = $$\frac{504}{18}$$​ = 28
