Question

2. If 4:6=6: x, then what is the value of x?
(A) 12 (B) 9 (C) 8 (D) 4​

Answer 1

Answer:

4:6::6:x

Since, product of means=product of extremes

4x=6×6

x=6×6/4

x=9

Option B is correct.

Answer 2

Value of x is 9 if 4:6=6:x

Given:

• 4 : 6 = 6 : x

To Find:

• Value of x

Solution:

• a : b :: c : d
• Product of extremes = Product of middles
• ad = bc

4 : 6 = 6 : x

Step 1:

Equate Product of Extremes with product of middles

4x = 6 × 6

=> 4x = 36

Step 2:

Divide both sides by 4

x =  36/4

=> x = 9

Value of x is 9

Correct option is B) 9
