A teacher organised the heights (in cm) of students into a tally chart. The four class intervals had tallies: 130-140: one bundle of five, 140-150: two bundles of five and one stroke, 150-160: one bundle of five and four strokes, 160-170: three strokes. What is the total number of students measured?

Question

Accepted Answer

28. 130-140 = 5; 140-150 = 10 + 1 = 11; 150-160 = 5 + 4 = 9; 160-170 = 3. Total = 5 + 11 + 9 + 3 = 28.
