Solution:
Let the time taken for one question be x
Then math question takes 2x
Remaining questions other than math questions are 150
then time taken for the remaining questions is 150x
Time taken to solve math questions = 50 × 2x = 100x
100x + 150x = 3 × 60
250x = 180
x = 180/250
Then time taken for math problems = 2 × 180/250 × 50 = 72
