Correct Answer : B

Let the numbers be \(a/r, a, ar\). Their product is \(a^3 = 64\), so \(a=4\). Their sum is \(a/r + a + ar = 14 \Rightarrow 4/r + 4 + 4r = 14 \Rightarrow 4/r + 4r = 10 \Rightarrow 4+4r^2=10r \Rightarrow 4r^2-10r+4=0 \Rightarrow 2r^2-5r+2=0 \Rightarrow (2r-1)(r-2)=0\). So \(r=2\) or \(r=1/2\). If r=2, numbers are 2, 4, 8. If r=1/2, numbers are 8, 4, 2.

Every number in the list is even except one.

\[ 10,\; 14,\; 16,\; 18,\; 24,\; 26 \;\text{are even} \]

\[ 21 \;\text{is odd} \]

So 21 is the odd man out.

Correct Answer : B

Correct answer: ₹768

Apply \[ \text{TD} = \frac{A \times RT}{100 + RT} \] with \( RT = 14 \times 2 = 28 \): \[ 168 = \frac{A \times 28}{128} \;\Rightarrow\; A = \frac{168 \times 128}{28} = 6 \times 128 = 768. \] The arithmetic simplifies neatly because \( 168/28 = 6 \), which is worth looking for before multiplying out. Checking: the present worth is \( 768 - 168 = 600 \), and the simple interest on 600 at 14% for 2 years is \( 600 \times 0.28 = 168 \) - the true discount as given. For completeness, the banker’s discount would be interest on the face value, \( 768 \times 0.28 = 215.04 \), and the banker’s gain the difference, 47.04 - which is also the interest on the true discount, \( 168 \times 0.28 \). The distractor 800 is the answer obtained by wrongly treating TD as interest on the face value.

Correct Answer : A

Trains in the same direction close at the difference of their speeds; in opposite directions, at the sum.

\[ 1 \text{ kmph} = \frac{5}{18} \text{ m/s} \]

\[ \text{relative speed} = 72 - 36 = 36 \text{ kmph} = 10 \text{ m/s} \]

\[ t = \frac{200 + 300}{10} = 50 \text{ sec} \]

Both lengths count, because the whole of one train must pass the whole of the other.

Correct Answer : A

The answer is Saraswati Saha Dey.

Saraswati Saha (born Saraswati Dey), the sprinter from Agartala, is recorded as Tripura's first Olympian. She was one of India's leading sprinters of her time and won the women's 200 metres gold at the 2002 Asian Games in Busan.

Dipa Karmakar, also from Agartala, became famous much later, at the 2016 Rio Olympics, where she was the first Indian woman gymnast to compete and finished fourth in the vault. The tennis player Somdev Devvarman, whose family is from Tripura, rose to prominence only in the late 2000s. So neither of them can be the state's first Olympian.

Fertilisation is the fusion of a male gamete with the egg cell.

The result is the diploid zygote. In flowering plants it follows the growth of the pollen tube down the style; the second male gamete fuses with the polar nuclei to form the endosperm, which is why the process is called double fertilisation.

Correct Answer : D

Correct answer: The state level

The Lokayukta is the anti-corruption ombudsman at the state level; its counterpart at the Union level is the Lokpal. States began creating Lokayuktas long before the centre acted: Maharashtra was first in 1971, followed by Odisha, Rajasthan, Bihar and others, each under its own statute, so their powers, tenure and jurisdiction have varied considerably. Karnataka’s was for a period the most active, with its own investigating police wing. The Lokpal and Lokayuktas Act of 2013 created the Lokpal and required every state to establish a Lokayukta within a year, though it left the details to state legislation. The institution derives from the Scandinavian Ombudsman, recommended for India by the first Administrative Reforms Commission in 1966, which proposed both a Lokpal and Lokayuktas. Neither is a constitutional body; both are statutory, which is one reason their independence and effectiveness have been questioned.
