$$\frac{75}{100}$$X = $$\frac{125}{100}$$Y

3X = 5Y.

Y = $$\frac{3}{5}$$X

Y = 0.6X.

Or Y is 60% of X.

75 percent of x equals 125 percent of y
Or, 0.75*x=1.25*y
Or, $$y=\frac{0.75}{1.25}*x$$
Or, y=0.60x
Or, y=60% of x

Ans. (C)

75% of x = 125% of y

75x = 125y

3x = 5y

y = $$\frac{3}{5}$$x.

y = 60% of x.

Note:$$\frac{3}{5}$$ = 60%

D. y is 140 percent of x
E. y is 166 2/3 percent of x

75% = 3/4

125% = 5/4

Now, 3x/4 = 5y/4

Or, 3x = 5y = 15 (Say)

So, x = 5 and y = 3

Thus, y is 60% of x, Answer must be (C)

0.75x = 1.25 y
3/4 x = 5/4 y :converted into faction for ease of cancellation
3 x = 5 y :cancelled both the denominators
3/5 x = y :converted to y format
.60 x = y :final answer C

Hi All,

We're told that neither X nor Y can equal 0 and that 75% of X is equal to 125% of Y. We're asked which of the following is true. This question can be solved in a couple of different ways, including by TESTing VALUES.

IF....
X = 100, then (75% of X) = 75

75 = 125% of Y
75 = 1.25(Y) = (5/4)(Y)
(4/5)(75) = Y
300/5 = Y
60 = Y

Thus, Y = 60 when X = 100
