Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

If x ∝ y and x = 66 when y = 3, then the value of constant of variation

• 22

• 33

• 44

• 11

EVALUATION

Here it is given that x ∝ y

∴ x = ky - - - - - - (1)

Where k is constant of variation

Now it is given that x = 66 when y = 3

We get from Equation 1

66 = k × 3

⇒ 66 = 3k

⇒ 3k = 66

⇒ k = 22

The constant of variation = 22

FINAL ANSWER

Hence the correct option is 22
