Q. 116. Which statement is false?

(A) All fractions are rational numbers

(B) All irrational numbers are real numbers

(D) All non-terminating decimals are irrational

Answer:

Explanation:

Q. 117. A right circular cone has radius $r/2$ and slant height $2l$ . Its total surface area equals:

(A) $2\pi rl$

(B) $2\pi (r+l)$

(D) $\pi r (r+l)$

Answer:

(C)

\pi r (l + r/4)

Explanation:

The total surface area of a cone is

\pi r_{new} l_{new} + \pi r_{new}^2

. Substituting radius

r/2

and slant height

2l

gives

\pi(r/2)(2l) + \pi(r/2)^2 = \pi r l + \pi r^2/4 = \pi r(l + r/4)

Q. 118. What is the length of the longest pole that fits inside a 10 m × 10 m × 5 m room?

(A) 8 m

(B) 12 m

(D) 15 m

Answer:

Explanation:

The longest pole is the space diagonal of the cuboid room:

\sqrt{10^2 + 10^2 + 5^2} = \sqrt{100+100+25} = \sqrt{225} = 15 m

Q. 119. The mean of five numbers is 30. If one number is excluded, the mean of the remaining four is 28. What is the excluded number?

(A) 28

(B) 30

(D) 38

Answer:

Explanation:

The sum of the 5 numbers is

30 \times 5 = 150

. The sum of the remaining 4 numbers is

28 \times 4 = 112

. The excluded number is

150 – 112 = 38

Q. 120. One end of a circle’s diameter is (2, 3); its centre is (-2, 5). What is the other end?

(A) (-6, 7)

(B) (4, 2)

(D) (6, 7)

Answer:

Explanation:

Let the other end be

(x,y)

. The center is the midpoint:

(x+2)/2 = -2 \Rightarrow x = -6

and

(y+3)/2 = 5 \Rightarrow y = 7

. The other end is

(-6, 7)
