Question

if R is directly proportional to Y and x is equal to 66 when Y is equal to 3 then what will be the volume of constant of variation​

Answer 1

For direct variation, use the equation y = kx, where k is the constant of proportionality. For inverse variation, use the equation y = k/x, again, with k as the constant of proportionality. Remember that these problems might use the word 'proportion' instead of 'variation,' but it means the same thing.
