  1. 23
  2. 33
  3. 24
  4. 34

hintHint:

Find by partial sum method.
To find partial sums add the digits in tens place and ones place seperately.

The correct answer is: 34


    15 students like to play soccer and 19 students like to play tee-ball. 
    Total number of students = 15 + 19
    To find partial sums add the digits in tens place and ones place seperately.
    Partial sum of 15 + 19
    Step 1 : Add digits in tens and ones place seperately:
    10                                    05
    + 10                   and        + 09

    _____                             ______
    20                                        14
    Thus, the sum of 15 + 19 are 20 + 14 = 34.

    So, there are 34 students in all.
