The total number of hours studied in 10 days is 22 hours. Now the question says jimmy has either studied 2 hours a day or 3 hours a day. To find this the calculation is as follows:
For eight days jimmy has studied for 2 hours, so the total time that he has studied makes up to be 16 hours. Now for the other two days jimmy has studied for 3 hours which adds up to be 6 hours. So the total time studied is 6 hours.
Total= 16+6=22 hours
