RE: A and B write a testA says " i got a third of the ques. wrong"B says " i got 5 wrong"together they got three quarters of the questions correct.how many did a get correct.
|
A got 1/3 of the questions wrong it means 33%
So A got 67% correctly
When A got 67% correct and Total A and B is 75%
Then B's Correct is 83%
Therefore B's Wrong is 17%
and The total No. of questions where 5/.17=30
I am sure the qustions are same for A and B
Therfore 1/3 of 30 is 10 and A got 20 questions correct
Hope I am correct |
