let the no of questions be x
a got x/3 answers wrong
b got 5 answers wrong

together they got 3x/4 right answers so x/4 wrong answers
(x/3)+5 = x/4
x=60

30 questions.

suppose there were x questions, then
Correct answers by A = 2x/3
Correct answers by B= x-5
As per given condition

(x-5)+ 2x/3 = 2*3x/4

solving it, we get x=60

5 questions

3/4*2x because they got the 3/4 of answers right together...so number of questions also double up ie 2x

Correct answers by A = 2x/3
Correct answers by B= x-5
As per given condition

(x-5)+ 2x/3 = 2*3x/4
hence x = 30

Hi PARGAT PAL Singh, solving your equation we do not get x = 60, we get x = 30, your previous answer was right.

A got 2/3(x) answers correct
both A and B got 3/4 answers coorect i.e they got /4 wrong
A+B=1/4
1/3+B=1/4
B=1/12
1/12(x)=5
x=60.
answer is 60

for a no of questions be x
for b no of questions be y
only wrong questions be
x/3+5=(x+y)/4
if x and y are same, then
x/3+5=x/2
x=30
if x and y are not same
2x/3+(y-5)=3(x+y)/4
from above we get 2 equations
we get x and y
