Once you attempt the question then PrepInsta explanation will be displayed.
The starting figure we start with when we read the first statement is: Monday Tuesday Wednesday Thursday Friday Saturday Workouts are cycling, rowing, gymnasium, jogging and boxing. From the second and third clues (gymnasium workout is done neither on the first nor on the last day but was done earlier than rowing and jogging was done on the day immediately following the rowing day), we know that rowing and jogging should be together and also that gymnasium has to be somewhere before this. Visually this can be represented as:
From the fourth and sixth clues we have: C-Rest day-B Note: Putting it in a box signifies that there is no break between the items in the box. Once we have these two visual representations we can go back to our original figure and think as follows: Monday Tuesday Wednesday Thursday Friday Saturday Since gymnasium has to precede rowing and jogging, and gymnasium is not on the first day we can have 3 possibilities for placing gymnasium—viz: Tuesday, Wednesday or Thursday.
