Answer / harsh
3 hrs=180 mins
suppose time alloted for each que=1 unit
the time alloted to a que other than mathematics=(200-50)
=150 units
since the time spent on a maths question is twice the other
problems, time spent on a maths prob= 50*2=100 units
therefore, 2/5 or [100/(150+100)] of the total time will be
spent on a maths prob
ie 180*(2/5)
=72 mins

Answer / kishore
50 maths ques
150 remaining ques
the time spent on each math ques is twice the remaining
150x+50(2x) = 180 (min)
x= 18/25
total time on maths ques is 50(2x)
50 * 2 * 18/25 = 72min

Answer / ashraf
we assume that X is the time taken for each general question
then the time taken for math problem is 2X
then 150X+50(2X)=3hours
then x=(3*60)/250 min
x=18/25 min
then the time taken for math problem is 2X=2*18/25=36/25

Answer / r.subha
total 200 questions, time duration 3 hours so,1 hour =60 min
so,3 hours=180 mins.
out of 200 questions 50 questions is maths question 150
question is other question.
if you spent x time for 150 question, you spent 2x time for
50 question
so, 50(2x)+150(x)=180
solve ,we got the x value ; x=18/25
150 question 150 x ,we have calculate 150 questions time
so 150(18/25)=108
then total time is 180, we had spent 108 minute for 150
question,so
180-108=72. remaining minute for 50 question is 72
