Question

If 5 : 7 : : y : 35, find the value of y.

Answer 1

5 : 7 : : y : 35

Product of means = product of extremes

So Here,

Extremes are 5 and 35

and means are 7 and y

Therefore,

Product of means = product of extremes

7 * y = 5 * 35

7y = 175

y = 175/7

y = 25

Hence, the value of y = 25.

Answer 2

Answer:

=> The value of y is 25.

Step-by-step explanation:

Given that:-

$5:7::y:35$

We have to calculate the value of y,

Given ratio is written as,

$=>\frac{5}{7}=\frac{y}{35}$

By using cross multiplication,

So, we will get

=> 7 $\times$ y = 5

=> 7y = 175

Now, divide both sides by 7 we get

=> y = 25

Hence, the value of y is 25.
