Question

If x is 15 when y = 25 , then find x when y =87

its urgent

Answer 1

Since

x is 15 when y = 25

=> y is 25 then x is 15

=> If y will increase then x will increase

=> y is proportional to x

Let the constant term be k

=> 25 = k x

=> 25 = 15 k

=> k = 25/15

=> k = 5/3

So when y = 87
k = 3/5 then x = ?

=> 87 = 5/3 x

=> x = 87 × 3/5

=> x = 52.2


Hope it helps dear friend ☺️✌️
