Answer:  Time spent on Question C=3  9/10

Step-by-step explanation:

Total Time to do the entire quiz= 20 minutes

Time spent on Question A=10 7 /10 minutes

Time spent on Question B=5 2/ 5 minutes

Time spent on Question C=Total Time to do the entire quiz-(Time spent on Question A+Time spent on Question B)

20mins- (10 7 /10  +5 2/ 5)

20mins - (  15  7+4 /10)

  20mins - ( 15 11/10=16 1/10))

20mins -16 1/10

19 10/10 -16 1/10

Therefore Time spent on Question C= 3 9/10
