3*60 = 180 minutes

2x = minutes spent on a math problem


\(x(200-50) + 2x(50) = 180
x(150) + 2x(50) = 180
150x + 100x = 180
250x = 180
x = 0.72\) minutes

C is the answer

Maths problems: 50
Other problems: 200 - 50 = 150

Let time for other problems: x
time for maths problems: 2x

50(2x) + 150(x) = 60 * 3
100x + 150x = 180
250x = 180
x=18/25

Time spent on maths: 50(2x) = 100x = 100 * 18/25 = 72 mins
