Question 8 Mudhol Hounds (a type of breed of Indian dogs) are largely found in North Karnataka’s Bagalkote and Vijaypura districts. The government took an initiative to protect this breed by providing support to those who adopted these dogs. Due to this initiative, the number of these dogs increased. The number of Mudhol dogs in six villages of Karnataka are as follows — Village A : 18, Village B : 36, Village C : 12, Village D : 48, Village E : 18, Village F : 24 Prepare a pictograph and answer the following questions: (a) What will be a useful scale or key to draw this pictograph? (b) How many symbols will you use to represent the dogs in Village B? (c) Kamini said that the number of these dogs in Village B and Village D together will be more than the number of these dogs in the other 4 villages. Is she right? Give reasons for your response. Now to make Pictograph, we need a scale Our data is Village A : 18, Village B : 36, Village C : 12, Village D : 48, Village E : 18, Village F : 24 We note that all numbers are multiples of 6, so we assume 1 dog image = 6 animals (a) What will be a useful scale or key to draw this pictograph? A useful scale would be 1 symbol = 6 dogs, as all the numbers are multiples of 6. (b) How many symbols will you use to represent the dogs in Village B? We will use 6 symbols for Village B (36 / 6 = 6). (c) Kamini said that the number of these dogs in Village B and Village D together will be more than the number of these dogs in the other 4 villages. Is she right? Give reasons for your response. Yes, Kamini is right. Village B + Village D = 36 + 48 = 84 dogs. Other 4 villages = 18 + 12 + 18 + 24 = 72 dogs. 84 is more than 72, so she is correct
