Question

The value of y is directly proportional to the value of x. If y = 35 when X = 140, what is the

value of y whenx=70?

Answer 1

17.5

Explanation:

soln:

given,

since, x and y are directly proportional

and x=140, y=35

dividing x by y we get,

x/y=140/35

or,x/y=4/1

or,x=4y

when x=70,

x=4y

or,70=4y

•°•y=17.5
