Q4.Rohan wanted to find the value of y when x=12, given that x and y are directly proportional. He knew that when x=4, y=10. His working was: (4 × 10) = (12 × y) => 40 = 12y => y = 40/12 = 10/3. What mistake did Rohan make?

A.He should have used (x + y) = constant.

B.He incorrectly assumed x and y are inversely proportional.

C.He made a calculation error in the final step.

D.He should have set up the equation as (4/10) = (12/y).

Difficulty: Easy
