On a certain transatlantic crossing, 20 percent of a ship's passangers held round-trip tickets and also took their cars aboard the ship. If 60 percent of the passangers with round trip tickets did not take their cars aboard the ship, what percent of the ship's passangers held round-trip tickets?

33.3%
40%
50%
60%
66.6%

Let # of ppl with round trip tickets be x.
# of ppl with round trip tickets who did not take their cars aboard the ship = 0.6x
# of ppl with round trip tickets who took their cars aboard the ship = 0.2

0.2+0.6x=x => x=50%

What is OA?

0.2+0.6x=x
=> 0.2= (x-0.6x)
=> 0.2=0.4x
=> x= (0.2/0.4)
=> x= 1/2
=> x=50%

Is this what you asked?

0.2+0.6x=x
=> 0.2= (x-0.6x)
=> 0.2=0.4x
=> x= (0.2/0.4)
=> x= 1/2
=> x=50%

Is this what you asked?


Yeah there is another explanation saying that u take 0.2 and compare it to 40% of those who didnt take their car which takes u to x=0.2/0.4 =50%

I didnt notice u can actually solve it by the way u did it
cool

Sorry, I usually use a 2D matrix for solving these kind of problems and I didn't draw that in my post.
I converted everything into decimals (rather than keeping it in percentage).
