Numbers which are divisible by 6 between 10 and 50 are
12, 18, 24,30, 36, 42, 48
Hence 7 numbers are divisible by 6.
Question 3 :
Find the product of 1.008 x 7
(A) 5.012 (B) 6.026 (C) 7.056
Solution :
1.008 x 7 = 7.056
Question 4 :
Which of the following is correct?
(A) 0 < -1 (B) 0 > -5 (C) -3 > 0
Solution :
Negative numbers are lesser than 0. So, 0 < -1 is correct.
Question 5 :
Joseph earned $20.70 for working 6 hours. How much was he paid for an hour?
(A) $5.15 (B) $3.45 (C) $2.25

Question 6 :
The area of a picture is 240 sq.cm. Its length is 20 cm. What is the breadth?
(A) 18 cm (B) 15 cm (C) 12 cm
Solution :
Area of picture = 240
length = 20 cm, breadth = ?
Area of the rectangle = length x breadth
20 x breadth = 240
Breadth = 240/20
Breadth = 12 cm
Question 7 :
Find the greatest common factor of 15, 35 and 75 ?
(A) 305 (B) 615 (C) 525
Solution :
Greatest common factor = 5⋅3⋅7⋅5
= 525
Question 8 :
The value of 3 cubed times 2 squared is
(A) 108 (B) 102 (c) 110
Solution :
3 cubed times 2 squared = 3^{3 }⋅ 2^{2}
= 9 ⋅ 4
= 36
Question 9 :
If A = {2, 4, 6, 8} then what will be the value of n(A)
(A) 4 (B) 7 (C) 10
Solution :
The number of elements in the set A is 4.
The value of n(A) = 4
Question 10 :
What is the value of 6!
(A) 540 (B) 720 (C) 120
