ANSWERS:

1. a) Price of 1 kg tomatoes = 8 rupees
   Price of ½ kg tomatoes = 4 rupees.
   b) Price of 1 kg onions = 10 rupees
   Price of ½ kg onions = 5 rupees
   Price of 1kg carrot = 16 rupees
   Price of ¼ kg carrot = 4 rupees.
   So ½ kg of onion is more than ¼ kg of carrot.
   c) Price of 1 kg potatoes = 12 rupees
   Price of ¾ kg of potatoes = 9 rupees.
2. Price of 1 kg potatoes = 12rupees
   Price of ½ kg potatoes = 6 rupees
   Price of 1 kg pumpkin = 4 rupees
   Price of 2kg pumpkin = 2 x 4 = 8 rupees
   Price of 1kg carrot = 16 rupees
   Price of ¼ kg carrot = 4 rupees
   Total = 6 + 8 + 4 = 18 rupees.
   So Keerthi can buy all the things in her shopping list.
3. Price of 1 kg tomatoes = 8 rupees
   Price of 2 kg tomatoes = 2 x 8 = 16 rupees
   Price of 1 kg potatoes = 12 rupees
   Price of ½ kg potatoes = 6 rupees
   Price of 1 ½ kg potatoes = 12 + 6 = 18 rupees
   Total = 16 + 18 =34 rupees.
4. Manu travels more by 1 ½ km.

   Number of boys = ½ of 38 = 19
   Number of girls = 38 – 19 = 19.
8. Total number of balls = 20
   Number of red balls = ½ of 20 = 10
   Number of blue balls = ¼ of 20 = 5
   Number of green balls = ¼ of 20 = 5

   Price of 1 kg sugar = 30 rupees
   Price of 2 kg sugar = 2 x 30 = 60 rupees
