Question

Maria did 25 sets of

15 jumping jacks,
18 sets of 20 sit-ups,
21 sets of 12 push-ups,
and 16 sets of
10 pull-ups.
How many times did Maria do
each exercise?

Answer 1

1,147 times

Explanation:

15 jumping jacks per set. 25 sets = 25 × 15 = 375

20 sit-ups per set. 20 sets = 20 × 18 = 360

12 push-ups per set. 21 sets = 21 × 12 = 252

10 pull-ups per set. 16 sets = 16 × 10 = 160

375 + 360 + 252 + 160 = 1147
