Two quantities, x and y, are directly proportional. If x is halved, what happens to y? clear check it is doubled. It is squared. It is multiplied by 12. It depends on the starting value of x.

DIRECTLY PROPORTIONAL: connected, i.e., one grows or shrinks in proportion to the other. His income is directly correlated with the number of units he sells.

If we spend Rs. 50 on two pens, as an example.

For four pens, it will cost us 100 Rs.

When the ratio x:y1 is constant, two values, x and y, are said to be inversely proportional to one another.

So, if a relationship between two variables, x and y, can be represented in the form y/x = k OR y = kx, it represents a proportionate variation.

Then,

If x rises, y will follow.

If x declines, y will follow.

So, we obtain:
When x is cut in half, y does as well.

Therefore, when x and y are directly proportional and when x is halved then y is also halved or (C) it is multiplied by 1/2.
