Question

If x and y are directly proportional, find the value of x 1, x 2 and y 2 in the table given below: X 3 x 1, x 2 10 Y 72 120 192 y 2

Philoid · Accepted Answer

We use the relation Here x₁ = 5, y₁ = 210 and x₂ = 2

Here,

⇒ x₁ × 72 = 3 × 120

⇒ x₁ = = 5

Now,

⇒ x₂ × 72 = 3 × 192

⇒ x₂ = = 8

And

⇒ y₂ × 3 = 10 × 72

⇒ y₂ = = 240
