Marks 80      Time: 2.5 hours

Q 1 Choose the correct options:

1) The correct fraction for 8 hours and a day is

a) 1/4

b) 1/3

c) 1/8

d) 1/6

Solution: Now 1 day = 24 hours. So what is the fraction of 8 hours to 24 hours which is 8/24 = 1/3 so answer is 1/3

2) _______ is the perimeter of a triangle with sides 4-6-8

a) 12

b) 18

c) 32

d) 20

Answer: Perimeter is nothing else but summation of sides, therefore we get: 4+ 6 + 8 = 18

Hence the answer is 18

3) What is the area of a square with side 1 cm?

a) 1 cm2

b) 10 cm2

c) 100 cm2

d) 11 cm2

Answer: Area of a square is s2 where s = length of 1 side. There for area of 1 cm side = 1 x 1 = 1 cm2

4) Expression for -p divided by 8 is ____________

a) -p/8

b) -8/p

c) -8p

d) -8+p

Solution: This is an example of algebra equation. In std VI we have elementary algebra and equations.

Here -p divided by 8 is -p/8 that is the answer

5) The solution of the equation x + 7 = 10 is

a) 2

b) 1

c) 3

d) 4

Solution: x+ 7 = 10 therefore taking 7 on right hand side the sign of 7 changes to -7 so we get

x = 10-7 = 3

6) Ram earns Rs. 1500 and spends Rs. 150, what is the ratio of earning to expenditure

a) 10: 1

b) 1: 10

c) 1500 : 1

d) 1: 150

Solution: Ratio of earning to expenditure = 1500/150 = 10 / 1 which in ratio form we get 10 : 1

7) The diameter of a circle is 0.02 mt. The radius is to be ____ mt.

a) 0.01

b) 0.04

c) 0.1

d) 0.4

Solution: Radius of circle  = diameter of circle/2 = 0.02 /2 = 0.01 mt

8) The square has _______ symmetrical lines

a) 2

b) 4

c) 3

d) 5

9) The cost of 2 notebooks is Rs. 12; the cost of 8 note books is _____ Rs.

a) 20

b) 120

c) 48

d) 60

Solution: Use cross multiplication

Rs. 12 ======= 2 notebooks

?        ========= 8 notebooks

Therefore ? x 2 = 12 x 8

? = 12x 8 /2 = 48 Rs.

10) Radius is what fraction of diameter?

a) 1/2

b) 1/4

c) 3/4

d) 2/3

Solution: Radius is half of diameter, therefore in fraction we have 1/2
