Statistic Exercise 19.1 Solution
Question no – (1)
Solution :
(i) Given, What dose the pictograph represent
= It represent toys owned by 5 children
(ii) Given, Who owns the minimum number of toys
= Ansul owns minimum number of toys
(iii) Given, Who owns the maximum number of toys
= Sonam owns maximum number of toys
(iv) Given, How many more toys does Priyanka own that Ansul
= (20 – 10)
= 10
∴ Priyanka owns more toys.
(v) Given, How many toys, in all , do the five children own

= 85
∴ Five child own 85 toys
(vi) Given, What is the scale
= One picture represent 5 toys.
Question no – (5)
Solution :
(i) Given, What is the scale of the bar graph
= Scale 14 inch.
= 10 families.
(ii) Given, What is the information given by the bar graph
= It shows the number of families with different number of in a locality.
(iii) Given, How many members per family are there in the maximum number of families? Also tell the number of such families
= 3 members per family in maximum family.= 120 family.
(iv) Given, What is the number of families having 4 members
= 100 families having four members.
(v) Given, What are the number of members per family for which the number of family are equal? also tell the number if such family.
= 8, 9, 10 member per family having equal number of families
= 10 families.

(iv) What was the production of off grains in the year 1989 – 90
= 100 million tons food grains in the 1989 – 90.
(v) Does the bar graph indicate increase in the production with the passage of time
= No
(vi) What is the scale of the graph
= 1 cm
= 10 million tons

= 1 cm represent 10 cm of rain.
(iii) What information in represented by the bar graph
= Rainfall during 1995.
(iv) In which month was the rainfall maximum? What is the maximum rainfall in that month
= In family the rain full maximum.
= 50 cm rainfall
(v) What was the rainfall in October
= 30 cm rainfall
(vi) Which month was the most dry
