In interpreting a pictograph, we get a lot of information regarding the pictograph items. The following examples may illustrate the interpretation of pictographs.

**A. **The following pictograph shows how many cars were washed at the washing center of a service station during four days of a week. **Solution: **

We can get information from the pictograph by asking the following questions:

**1.** How many cars were washed on different days?

(On Monday 4 x 5 = 20 cars,

On Tuesday 8 x 5 = 40 cars,

On Wednesday 6 x 5 = 30 cars,

On Thursday 5 x 5 = 25 cars)

**2.** On which day were the maximum numbers of cars washed?

(On Tuesday maximum numbers of cars (40) were washed)

**3.** On which day were the minimum numbers of cars washed?

(On Monday: 20 cars)

**4.** How many more cars were washed on Tuesday than Wednesday?

(40 - 30 = 10 more cars)

**5.** How many total cars were washed in four days?

(20 + 40 + 30 + 25 = 115 cars)

**B. **There is a pictograph showing rainfall of different cities
named (A, B, C, D, E and F) during the current year. On the basis of
this pictograph answer the following questions.

**Solution:**

This symbol represents 25 cm. of rainfall.

Pictograph showing rainfall in cm.

**1.** Give the information regarding rainfall in cities A, B, C, D, E and F in cm. **2.** In which city was there maximum rainfall? **3.** In which city was there minimum rainfall? **4.** The city A recorded how much more rainfall than the city F? **5.** Compare the rainfall between the city B and E. **Solution: ****1.** (i) In city A 7 x 25 = 175 cm

(ii) In city B 10 x 25 = 250 cm

(iii) In city C 6 x 25 = 150 cm

(iv) In city D 2 x 25 = 50 cm

(v) In city E 3 x 25 = 75 cm

(vi) In city F 1 x 25 = 25 cm

**2.** Maximum rainfall occurred in city B, i.e., 250 cm. **3.** Minimum rainfall was in city F that is 25 cm. **4.** Difference between rainfalls of city A and F = 175 - 25 = 150 cm.City A has more rainfall. **5.** The rainfall in city B was 250 cm, and in city E it was 75 cm. So, city B recorded more rainfall than city E.
