Question

find k if 20 , 18 , k , 36 are in proportion​

Answer 1

Answer:

Product of means = Product of extreme

= 18 × k = 20 × 36

= 18k = 720

= k =. 720/18

= (k = 40 )

Answer 2

Answer:

To find K if 20 , 18 , k , 36 are in proportion

20 : 18 : : K : 36

Product of extremes = Product of means

20 × 36 = K × 18

720 = K × 18

720÷18 = K

40 = K

Hence, K = 40
