Answers:
1.Answer: C
X2 − X – 42
= X2−7X + 6X – 42
= X (X−7)+ 6(X−7)
= (X+6) (X−7)
2.Answer: C
Let the present age of Sagul = X years
8years ago, his age was = (X – 8) years
According to given condition,
× (X – 8) = X
11 × (X – 88) = 4X
11X – 88 = 7X
4X = 88
X = 22
Age of Sagul at his marriage is 22 years.
3.Answer: B
Sum of the given numbers = 2 + 3+2 +9+ 2 + 4 + 6 + 7 +7 = 42
Mean of the given values = 42/9 = 4.67
4.Answer: b
5.Answer: C
6.Answer: C
7.Answer: A
8.Answer: B
Time taken by Sankar to the Savita = 150 : 100
Let x be the number of days taken by Sankar to do a piece of work
=>150 : 100 = 3:2
⇒ x = 2 × 18/3 = 12
Sankar takes 18 – x = 18 – 12 = 6 times than Savitato do the same piece of work.
9.Answer: b
Length of the train = Relative speed between the train and the car × time taken
Relative speed of the train = (180 – 72) = 108 × 5/18 = 30 (∵ they are travelling in same direction)
∴ Length of the train = 30 × 50 = 1500 m
10.Answer: B
Length of a diagonal = √2 × side
Given, area of a square is 100 sq cm
⇒ side2 = 144
⇒side = 12 cm
Length of a diagonal = √2×12
= 12√2
