10. Sohan bought a dozen mangoes. ¼ of these mangoes are ripe. How many mangoes are ripe?

**ANSWERS:**

1. Cost of 1 kg apple = 120 rupees

Cost of 1 kg orange = 80 rupees

Cost of ¾ kg apple = ¾ of 120 = ¾ x 120 = 360/4 = 90 rupees

Cost of ½ kg oranges = ½ x 80 = 80/2 = 40 rupees

Cost of 1 ½ kg oranges = 80 + 40 = 120 rupees

2. a) Amount paid for chocolates = ½ of 200 = 100 rupees

b) Amount paid for book = ¼ of 200 = 50 rupees

c) Amount paid for pouch = ¼ of 200 = 50 rupees

3. a) 24/48 = ½ (24 is a common factor)

b) 4/20 = 1/5 (4 is a common factor)

4. The amount Manu had = 20 rupees

Amount he spend = 16.50 rupees

Remaining amount = 20 – 16.50 = 3.50 rupees

So he will get 3 one rupee coins and 1 half rupee coin.

5. a) 1/7, 2/7, 3/7, 4/7, 5/7, 6/7…………….

b) 1/3, 2/3, 3/3, 4/3, 5/3, 6/3 ………………

6. Total number of toffees = 10

Toffees given to his sister = 2/5 of 10 = 2/5 x 10 = 20/5 = 4 toffees

Toffees remaining with him = 10 -4 = 6 toffees

7. Total number of oranges = 27

Number of oranges given to Kiran = 4/9 x 27 = 12

Oranges left in the basket = 27 -12 = 15

8. Total distance has to travel = 2 ¼ + 2 ¼ = 4 ½ km

9. Total number of chocolates = 12

Each one will get the following number of chocolates:

Raji – ¼ of 12 = ¼ x 12 = 12/4 = 3

Sujatha – 1/3 of 12 = 1/3 x 12 = 12/3 = 4

Sheela – 1/6 of 12 = 1/6 x 12 = 12/6 =2

Manju – remaining 3 chocolates.

10. Number of mangoes that are ripe = ¼ of 12 = ¼ x 12 = 12/4 = 3 mangoes.
