Answer 2

To find :

Given 3 : 8 : : 5 : x and we have to find x

Answer :

    x = 40/3

    The required value is 9 : 24 : : 15 : 40

Solution :

Now, 3 : 8 : : 5 : x

    ⇒ 3/8 = 5/x

    ⇒ x = (5 × 8)/3

    ⇒ x = 40/3

Then, the ratio becomes

    3 : 8 : : 5 : 40/3

By multiplying 3 to each term, we get

 (3 × 3) : (8 × 3) : : (5 × 3) : (40/3 × 3)

           ⇒ 9 : 24 : : 15 : 40 ,

which is the required value.
