Question

if x is 150 % of y, then y is what percent of x+y​

Answer 1

Answer:

suppose

x = 150

y=100

then;

x+y= 150+100=250

(x+y) ÷y = (250/100) ×100

= 40%

Answer 2

Answer:

40%

Step-by-step explanation:

x=150% of y

=150/100×y

x=3/2×y

x+y=3/2×y + y

=5/2×y

Let the percentage be a.

a/100 × x+y = y

a/100 × 5/2×y=y. {y gets cancelled}

a/100 × 5/2=1

a=2×100/5

a=40%
