Question 1 of 10
1. Question
If x and y are irrational numbers, then x + y xy is
Correct
Answer: a)
If x = √2, y = – √2then x + y – xy = √2 –√2 – (√2) (–√2) = 2
If x = √2, y = √3 then x + y – xy = √2 + √3 – (√2) (√3) = √2 + √3 – √6
We can conclude that x + y – xy is a real number.
Incorrect
Answer: a)
If x = √2, y = – √2then x + y – xy = √2 –√2 – (√2) (–√2) = 2
If x = √2, y = √3 then x + y – xy = √2 + √3 – (√2) (√3) = √2 + √3 – √6
We can conclude that x + y – xy is a real number.

Question 5 of 10
5. Question
In a company, the salary of a sales executive is partly fixed and partly based on his sales. A sales executive earns Rs. 22000 in a month for selling 300 units and Rs. 20000 in the next month for selling 250 units. If he sells 400 units in a month then how much amount he earns per unit?
Correct
Answer: b)
Let the salary be Rs. x and commission is Rs. y per unit sold.
X+300y= 22000
X+250 y= 20000
Solving two equations, y = 40
Total for 400 units = x + 400y
=> X + 300 y + 100 y = 22000 +100 x 40 = 26000
Average earning per unit= 26000 / 400 = 65
Incorrect
Answer: b)
Let the salary be Rs. x and commission is Rs. y per unit sold.
X+300y= 22000
X+250 y= 20000
Solving two equations, y = 40
Total for 400 units = x + 400y
=> X + 300 y + 100 y = 22000 +100 x 40 = 26000
Average earning per unit= 26000 / 400 = 65
Question 6 of 10
6. Question
_____________is equivalent to right ___________whose base is a circle.
Correct
Answer: c)
Incorrect
Answer: c)
Question 7 of 10
7. Question
The nature of roots of the equation is 10x^{2} – 6x + 1 = 0
Correct
Answer: b)
B^{2} – 4AC = 36 – 4(10) (1) = – 4
As B^{2}– 4AC is negative the roots are imaginary.
Incorrect
Answer: b)
B^{2} – 4AC = 36 – 4(10) (1) = – 4
As B^{2}– 4AC is negative the roots are imaginary.
Question 8 of 10
8. Question
Catherine was born when her father was 20 years old. At present the product of ages of Catherine and her father is 125, what will be Catherine’s age after five years?
Correct
Answer: b)
Let Catherine’s age be x years
Her father’s age = (x+20) years
X (x+20) = 125
X = – 25 or 5
Catherine’s age after five years = 5+5 = 10 years
Incorrect
Answer: b)
Let Catherine’s age be x years
Her father’s age = (x+20) years
X (x+20) = 125
X = – 25 or 5
Catherine’s age after five years = 5+5 = 10 years

Answers :
1). Answer: a)
If x = √2, y = – √2then x + y – xy = √2 –√2 – (√2) (–√2) = 2
If x = √2, y = √3 then x + y – xy = √2 + √3 – (√2) (√3) = √2 + √3 – √6
We can conclude that x + y – xy is a real number.
