Question

15 : 20=12 : x then out of the following which one is the value of x ?​

Answer 1

Answer:

Step-by-step explanation:

Given that,

15 : 20 = 12 : x

Product of extremes = Product of means

15 × x = 20 × 12

x = ( 20 × 12 ) / 15

= 240 / 15

= 16 is the answer

Answer 2

Value of x is 16 if 15 : 20=12 : x

Given:

• 15 : 20=12 : x

To Find:

• Value of x from the following

• 1) 9
• 2) 16
• 3) 25
• 4) 22.25​

Solution:

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

15 : 20=12 : x

Step 1:

Equate Product of Extremes with Product of middles

15x = 20 (12)

Step 2:

Solve for x

3x = 4 (12)  ( Divide both sides by 4)

x = 4(4)   ( Divide both sides by 3)

x = 16        ( calculate product of 4 and 4)

Hence Value of x is 16

Correct option is 2)  16

( Although question is complete but lacks options which has been added

1) 9 ,  2) 16 ,  3) 25  ,  4) 22.25​ )
