2. The most abundant of all the cells in blood are:

(1) Neutrophils
(2) Erythrocytes
(3) Thrombocytes
(4) Leucocytes

Correct Answer: (2) Erythrocytes

Solution:Erythrocytes, or red blood cells, are the most abundant cell in the blood, accounting for about 40 to 45 percent of its volume.

Erythrocytes are tiny biconcave disks, thin in the middle and thicker around the periphery.
Leukocytes, or white blood cells, are generally larger than erythrocytes, but they are fewer in number.

3. Two ships are sailing in the sea on the two sides of a light- house. The angle of elevation of the top of the lighthouse is observed from the ships are 30° and 45° respectively. If the lighthouse is 100 m high, the distance between the two ships is:

(1) 200 m
(2) 173 m
(3) 273 m
(4) 300 m

Correct Answer: (3) 273 m

Solution:

Let AB be the lighthouse and ships are at point C and D.
AB = 100 metre

In △ABC,
tan 45° = AB / BC
⇒ 1 = 100 / BC ⇒ BC = 100 metre

In △ABD,
tan 30° = AB / BD
⇒ 1/√3 = 100 / BD
⇒ BD = 100 × √3
= 100 × 1.73 = 173 metre

Distance between two ships = CD
= BC + BD = 100 + 173
= 273 metre

4. In visual representation of a painting Germania wears a crown of Oak leaves, as the German Oak stands for:

(1) Rich heritage
(2) Diversity

6. Three unbiased coins are tossed. What is the probability of getting at most two heads?

(1) 7/8
(2) 1/4
(3) 3/8
(4) 3/4

Correct Answer: (1) 7/8

Solution:Three unbiased coins are tossed = n(S) = 2³ = 8
E = Event to get at most two heads
= {HTT, THT, TTH, HHT, HTH, THH, TTT}
n(E) = 7

Required probability:
P(E) = n(E) / n(S) = 7 / 8

7. The power of accommodation of the eye usually decreases with ageing. This condition is called as:

(1) Astigmatism
(2) Myopia
(3) Hypermetropia
(4) Presbyopia

Correct Answer: (4) Presbyopia

Solution:Presbyopia is the irreversible loss of the accommodative ability of the eye that occurs due to aging.

Accommodation refers to the ability of the eye to increase its refractive power of the crystalline lens in order to focus near objects on the retina.

Correct Answer: (4)

Solution:Total runs = 110
Runs made by running between the wickets:
= 110 - (3 × 4 + 8 × 6)
= 110 - (12 + 48) = 50

Required percent = (50 / 110) × 100
= (5000 / 11) ≈ 45.5%
