Answer 2

Solution :

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

We know that ,

If a × d = b × c then a , b , c , d

are in proportion .

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

Here ,

a = 25 , b = 30 , c = 40 , d = 50

Now ,

a × d = 25 × 50 = 1250

b × c = 30 × 40 = 1200

Therefore ,

ad ≠ bc

So, 25 , 30 , 40 , 50 are not in

proportion.
