Two teams participating in a competition had to take a test in a given time. Team
B chose the easier test with 300 questions, and team A the difficult test with 10%less questions. Team A completed the test 3 hours before schedule while team B completed it 6 hours before schedule. If team B answered 7 questions more than
team A per hour, how many questions did team A answer per hour?

• 18 qns/hr
  
  If t hrs is normal time,
  then
  270/(t-3) + 7 = 300/(t-6)
  
  so t = 18
  
  so Qns done by team A per hour = 270/15 = 18 qns.
  Qns done by team B per hour = 300/12 = 25 qns.
