​

Answer 1

Clearly there are 20 boys and 40 girls. Number of students behind Kamal in rank =60-17=43

Number of girls ahead of Kamal in rank =9

∴ Number of girls behind Kamal in rank =40-9=31

∴ Number of boys behind Kamal in rank = 43 - 31 = 12.

Answer 2

Step-by-step explanation:

• Let the number of girls be m and number of boys be 2m
• Also the total number of students in the class will be 17 + 20 – 1 = 36
• Now 2m + m = 36
•            3m = 36
•         Or m = 36/3
•         Or m = 12
• So the number of boys will be 2m = 2 x 12 = 24
• So total girls will be Sujata + 1 = 7 + 1 = 8
• So according to the question 7 girls are ahead of Sujata
• Therefore we get 12 – 8 = 4
• So 4 girls are after Sujata.
