Answer to Q132
Apple and Orange cost $250. The apple is $200 more than the orange. How much is the orange?
I could see a lot of people fell for the $50 for the orange but read the question again, it didn't say the cost of Apple is $200. If the cost of Apple is $200 then obviously that of orange will be 250 - 200 = $50, but like I said cost of Apple is not $200. The question said Apple is $200 more than Orange.
In fact, that is another way to prove $50 is not the correct answer, if Orange is $50 which makes Apple $200, then Apple is (200 - 50 = $150) more that Orange but the question said it should be $200.
Ok, enough of that, let's solve the question.
Apple and Orange cost $250
Let Apple = A
Let Orange = O
A + O = $250 (eqn 1)
The apple is $200 more than the orange
A = O + 200 (eqn 2)
How much is the orange? (AKA, find O)
putting eqn 1 and eqn 2 together
"O" + 200 + "O" = 250
2"O" = 250 - 200 (did 2"O" so you don't mistake that for twenty)
2"O" = 50
O = 50 ÷ 2
O = 25
So, Orange is $25 and that makes Apple $225
To check our answer, $225 - $25 = $200 (The apple is $200 more than the orange).
Answer: 25
