10. Evaluate:

a) (-2/3) x (-1/3)

b) (3/24) – (7/36)

**ANSWERS:**

1. -20/30

2. Binomial

3. 9.03

4. 8:1

5. -5

6. Number of children liked to play football = 25% of 40 = 10 children

7. Given length = 400m and breadth = 250m

Area of a rectangle = length x breadth = 400 x 250 = 100000 square metre

8. 20ab + 10b+10a –(12ab -5b-9a) = 20ab +10b+10a – 12ab + 5b + 9a = 8ab + 15b +19a

9. CP = 23500

SP = 21150

Since CP> SP, there is a loss of 23500 – 21150 = 2350 rupees

Loss% = (loss/CP) X 100 = (2350/23500) X 100 = 10%

10. a) (-2/3) x (-1/3) = 2/9

b) 3/24 – 7/36 = (9 – 14)/72 = -5/72.
