If the average number of calories burned by B on Thursday, Friday and Saturday together is 125, what will be the number of calories burned by B on Saturday?

Solution

Number of calories burned by B on Thursday = 135

Number of calories burned by B on Friday = 145

Average number of calories burned by B on Thursday, Friday and Saturday together = 125

=> Total number of calories burned by B on Thursday, Friday and Saturday together = 125 * 3 = 375

$$\therefore$$ Number of calories burned by B on Saturday = 375 - 135 - 145 = 95
