Answer:
given,
Number of questions attempted by the student =84
the questions which he did correctly=x
the questions which he did wrong (which is twice the wrong)=2x
According to the question
x+2x=84
3x=84
x=84/3
x=28
therefore, the questions which he did correct =28
(the technique for check our answer is,we will put the value of x in our equation, x=28,28+2×28=84
28+56=84
84=84 )))))
