Answer 2

Answer:

x = 80  

Step-by-step explanation:  

Given problem

Find x, if 5 : 10 : : 40 : x ​  

Here we need to find the value of x

given  5 : 10 : : 40 : x

here " : : " indicate 5 : 10 is proportional to 40 : x

⇒ if a : b is proportional to c : d

⇒    a : b : : c : d  then  ad = bc  

⇒ from given ratio  5x = 40 × 10

                                5x = 400

                                  x = 400 / 5 = 80
