Sol. Let us prepare a pictograph first as given below–

Shopkeeper’s Name Number of Kites Sold (1 = 50 kites)

Chaman

Rani

Rukhsana

Jasmeet

Jetha Lal

Poonam Ben

(a) 6 symbols represent the kites that Rani purchased.
(b) Poonam Ben purchased the maximum number of kites.
(c) In the pictograph, the number of symbols for Jasmeet is more than for Chaman. So, Jasmeet
purchased more kites.
(d) Yes, Rukhsana is correct.  Rani purchased 300 kites and Poonam purchased 700 kites. Double
of 300 is 600. Clearly, 700 is more than 600.
