Solution :

Q1.) (A)

Q2.) (C)

2x + 7y = 1 – (i)
4x + 5y = 11 – (ii)
2×(i) – (ii)
4x + 14 y – 4x –5y = 2 – 11
9y = – 9
y = -1
x = 4
(4,-1)

Q3.) (A)

At most one circle

Q4.) (C)

Hypotenuse = 2 × 15 = 30
Now check with option which follow Pythagoras Theorem.
18, 24, 30

Q5.) (D)

r = 7
D=2r =14

h = 6
D : h = 14 : 6 = 7 : 3

Q6.) (D)

Q7. (B)

If the radius of a right circular cylinder is changed by x% and height y% then change in volume

Negative sign shows decreases

Q8. (C)

Sum of the internals angles of the regular polygon

Q9.) (B)
Decrease in average = 2-month Total decrease =
Total age of new players = (17 + 20) years - 22 months = 35 years 2 month
Average age of new players = (35 years 2 month)2 = 17 year 7 month
