Question 982831
Hi there,
If it takes Hasan 1 min to do a Verbal question
and 1 minute 30 seconds to do a Mathematical question
then to do one question of each type = 2mins 30 secs
or 2.5 hours
If there is an equal number of questions then by dividing 
87.5 hours by 2.5 hours this would give 35 questions
So Hasan has 35 questions to answer.
Hope this helps:-)
