134, out of 182 countries of the world placing it at the same rank as in 2006.The HDI is based on three
indicators, namely Gross Domestic product GDP per capita (PPP US ), life expectancy at birth and
education as measured by adult literacy rate and gross enrollment ratio (combined for primary,
secondary and tertiary education). The value of Human Development Index for India gradually
increased from 0.427 in 1980 to 0.556 in 2000 and went upto 0.612 in 2007.

From the conversation Professor White's hair cannot be white for C, then it would his or her name nor
can it be black because he (she) replies to the black haired person. Therefore, it must be brown. If the
lady's hair isn't brown, then professor, White is not a lady. The remark from the black haired person can
be from Professor Black (for then the colour of hair would match his or her name) and cannot be from
Professor White as well (because the remark prompts an exclamation from white) Therefore, the black
haired person is jean Brown. Based on this the first statement from the lady is made by Professor Black.
Her hair cannot be black or brown. So, she has white hair.

46. The side of a square exceeds the side of another square by 2 cm and sum of the areas of the two squares
is 164 cm2. Find the dimension of the smaller square.
(a) 10cm
(b)9cm
(c) 8 cm
(d) 11 cm
Sol: (c) Let S1 and S2 be two squares. Let the side of the square S1 be x cm in length. Then, the side of
square S2 is (x + 2) cm.
Area of square S1 = x2sq cm
and Area of square S1 = (x + 2)3sq cm
According to the given condition,
Area of squares, + Area of square S2 =164 cm2
(x + 2)3 +x2 =164
x2 + 4x + 4 + x2 =164
2x2 +4x –160 = 0
x2+2x – 80 = 0
x2 + 10x – 8x – 80 = 0
x(x + 10) – 8(x + 10) = 0
(x + 10) (x – 8) = 0
x = – 10 or 8
x=8
So, the side of the smaller square is 8 cm.

Directions(Q. Nos. 53-56) Study the following paragraph carefully and answer the following questions
that follows.
When a rectangular coil carrying current is placed in a magnetic field, a torque acts on the coil which
rotates it continuously. When the coil rotates, the shaft attached to it also rotates and thus it is able to do
mechanical work. A DC motor consists of a rectangular coil made of insulated copper wire wound on a
soft iron core. This coil wound on the soft iron core forms the armature. The coil is mounted on an axle
and is placed between the cylindrical concave poles of a magnet.
The construction of electric motor is shown aside.
An electric motor is a device which converts electrical energy into
mechanical energy. A common motor works on direct current. So, it is
also called DC motor. When the coil is powered, a magnetic field is
generated around the armature. The left side of the armature is
pushed away from the left magnet and drawn towards the right,
causing rotation.
Motor losses are mainly due to resistive losses in windings, core losses and mechanical losses in
bearings, and aerodynamic losses, particularly where cooling fans are present, also occur. Losses also
occur in commutation, mechanical commutations spark and electronic commutators and also dissipate
heat. The efficiency of motor is the ratio of output to input power. When the coil turns through 900, the
brushes lose contact with the commutator and the current stops flowing through the coil. However the
coil keeps turning because of its own momentum. Now when the coil turns through 1800, the sides get
interchanged. As a result the commutator ring C1 is now in contact with brush B2 and commutator ring
C2 is in contact with brush B1 . Therefore, the current continues to flow in the same direction.
53. In the figure what does P and Q stands for?
(a) Brushes
(b) Armature
(c) Split rings
(d) None of the above
Sol: (c) P and Q stands for split rings.
54. Which principle is related with?
(a) II converts kinetic energy into potential energy
(b) It converts mechanical energy into electrical energy
(c) It converts kinetic energy into rotational energy
(d) It converts electrical energy into mechanical energy

Sol: (a)
CBSE - PSA
It converts electrical energy into mechanical energy.
55. The efficiency of the DC motor increases by
(a) decreasing the number of turns in the coil
(b) increasing the number of turns in the coil
(c) the number of turns in the coil is kept constant
(d) decreasing the strength of the current
Sol: (d) All types of lens are discussed in the passage i.e., concave and convex both.
56. What happens when the coil turns through 180°?
(a) Current flows in the opposite direction
(b) The sides of commutator remain same
(c) The sides of commutator get interchanged which results current flow in the same direction
(d) The sides of commutator get interchanged which results current flow in the opposite direction
Sol: (d) The sides of commutator get interchanged which results current flow in the same direction.
Directions(Q. Nos. 57-60) Study the following paragraph carefully and answer the following questions
that follows.
The Universe is commonly defined as the totality of existence, including planets, stars, galaxies the
contents of intergalactic space and all matter and energy. The broadest definition of universe is that it is
simply everything, while a narrower definition is that the universe is limited to what can be observed.
Similar terms include the cosmos, the
world and nature. Scientific observation of the Universe, the observable part of which is about 93 billion
light years in diameter, has led to inferences of its earlier stages. These observations suggest that the
Universe has been governed by the same physical laws and constants throughout most of its extent and
history. The Big Bang theory is the prevailing cosmological model that describes the early development
of the Universe, which in physical cosmology is calculated to have occurred 13.79 ± 0.037 billion years
ago.
At the heart of the solar system is our sun. The tour planets nearest it are rocky, terrestrial worlds—
Mercury, Venus, Earth and Mars. After that arc four gas giants: Jupiter, Saturn, Uranus and Neptune.
Between the orbits of Mars and Jupiter lies the asteroid belt, which includes the dwarf planet Ceres.
Beyond the orbit of Neptune one finds the disk-shaped Kuiper belt, in which dwarf planet Pluto resides,
and far beyond that is giant, spherical OortCloud and the
teardrop-shaped heliopause. The sun is by far the largest object in our solar system, containing 99.8% of
the solar system's mass. It sheds most of the heat and light that makes life possible on Earth and possibly
elsewhere. Planets orbit the sun in oval-shaped paths called ellipses and the sun is slightly off to the side
of the center of each ellipse. The inner four planets: Mercury, Venus, Earth and Mars arc made up mostly
of iron and rock. Asteroids are minor planets, most of which circle the sun in a region known as the

than750,000 asteroids in the belt with diameters larger than three-fifths of a mile (1 Ion), and they are
millions of smaller asteroids.
