Question

51 :85::57:x
find the value of x in each case of the following properties ​

Answer 1

Step-by-step explanation:

Given: 51:85::57:x

to find the value of x

solution = 51:85::57:x

= 51/85=57/x

=51x= 4845

= x = 4845/51

= x = 95

Answer 2

Answer:

Given proportion of 2 ratios = 51 : 85 : : 57 : x

We know that product of means is equal to product of extremes.

(a : b : : c : d is equal to bc = ad)

So, we can find the value of x by substituting the values.

⇒ 51 : 85 : : 57 : x

⇒ 85 * 57 = 51 * x

⇒ 4845 = 51x

⇒ $\frac{4845}{51}$ = x

⇒ 95  = x

∴ The value of x in the given proportion is 95.

Thnx and have a nice day!
