A series of problems in reasoning in arithmetic which were given in twenty-six school systems by Dr. C.W.  Stone furnish a valuable test in this field, as well as an opportunity for comparison with other schools in which these problems have been used.[22] A list of problems follows.

     Solve as many of the following problems as you have time for;
     work them in order as numbered: 

     1.  If you buy 2 tablets at 7 cents each and a book for 65
     cents, how much change should you receive from a two-dollar
     bill?

     2.  John sold 4 Saturday Evening Posts at 5 cents each.  He kept
     1/2 the money and with the other 1/2 he bought Sunday papers
     at 2 cents each.  How many did he buy?

     3.  If James had 4 times as much money as George, he would have
     $16.  How much money has George?

     4.  How many pencils can you buy for 50 cents at the rate of 2
     for 5 cents?

     5.  The uniforms for a baseball nine cost $2.50 each.  The shoes
     cost $2 a pair.  What was the total cost of uniforms and shoes
     for the nine?

6.  In the schools of a certain city there are 2200 pupils; 1/2 are in the primary grades, 1/4 in the grammar grades, 1/8 in the High School, and the rest in the night school.  How many pupils are there in the night school?

     7.  If 3-1/2 tons of coal cost $21, what will 5-1/2 tons cost?

     8.  A news dealer bought some magazines for $1.  He sold them
     for $1.20, gaining 5 cents on each magazine.  How many
     magazines were there?

     9.  A girl spent 1/8 of her money for car fare, and three times
     as much for clothes.  Half of what she had left was 80 cents. 
     How much money did she have at first?

     10.  Two girls receive $2.10 for making buttonholes.  One makes
     42, the other 28.  How shall they divide the money?

     11.  Mr. Brown paid one third of the cost of a building; Mr.
     Johnson paid 1/2 the cost.  Mr. Johnson received $500 more
     annual rent than Mr. Brown.  How much did each receive?
