Answer : Option D
Explaination / Solution:
Q2. Given that x is an integer, find the values of x which satisfy both 2x + 3 > 7 and x + 4 < 10
Answer : Option C
Explaination / Solution:
Since x is an integer the solution set
Since x is an integer the solution set =
Hence the integer values which satisfy both the inequalities are
Q4. The first, second and last terms of an A.P. are a, b and 2 a. The number of terms in the A.P. is
Answer : Option C
Explaination / Solution:
Q5. The measure of variation which is least affected by extreme items is
Answer : Option C
Explaination / Solution:
as it only depends on upper and lower quartile not on extreme values
Q6. The acute angle between the lines x – y = 0 and y = 0 is
Answer : Option B
Explaination / Solution:
Slope of the line x - y = 0 is 1. This imlpies the tan = 1 Hence the angle made by the line with X- axis is 450
The angle made by the line y = 0 with the Y axis is 900
Therefore the acute angle between the lines is 450
Q7. Which of the following is logically equivalent to p↔q ?
Answer : Option B
Explaination / Solution:
By definition p↔q=(p→q)∧(q→p)
Q8. For each n N , is divisible by :
Answer : Option A
Explaination / Solution:
When n = 1 the value is 7.
Q9. The line y = mx + 1 is a tangent to the parabola if m =
Answer : Option B
Explaination / Solution:
The contion for a line to be a tangent to the parabola is y = mx +
From the given equation of the parabola we infer that a = 1 and from the equation of the line c = 1
Therefore m = a/c = 1
Q10. Angles of triangle are in A.P. If the number of degrees in the smallest to the number of radians in the largest is as 60:π, then the smallest angle is
Answer : Option A
Explaination / Solution:
