Question

3, 21, 5, 35, Verify that if the given digits are in proportion or not.

Answer 1

Hello !

Here is your answer !

the given digits will be in proportion if the product of the mean is equal to the product of the extreme

So in above question


3 × 35 = 105 (Product of extreme)

21 × 5 = 105 (Product of means )


Same So the Given Digit is in Proportion !

Hope it helps

Answer 2

Solution :

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

We know that ,

If a × d = b × c then a, b ,c ,d are

in proportion

*************************************
Here,

a = 3 , b = 21 , c = 5 , d = 35

a × d = 3 × 35 = 105

b × c = 21 × 5 = 105

Therefore ,

a × d = b × c

So , 3 , 21 , 5 , 35 are in proportion.
