Here is your answer !


Product of means = 8 × 10 = 80

Product of extremes = 4 × 20 = 80


Both Equal so it is in proportion

Answer 2

Solution :

************************************

We know that ,

If a × d = b × c then

a , b , c , d are in proportion.

************************************

Here ,

a = 4 , b = 8 , c = 10 , d = 20 ,

Now ,

a × d = 4 × 20 = 80

b × c = 8 × 10 = 80

Therefore ,

ad = bc

Given Numbers are in proportion.
