Correct Answer : C

The sum of the digits of \(x\) is 16. The least number divisible by 11, 21, 24 and 28 is their LCM: \[ \text{LCM}(21,24,28) = 168,\quad 168 \times 11 = 1848 \] So \(x = 1848k + 10\). Since \(1848 = 37\times 49 + 35\), we have \(1848 \equiv -2 \pmod{37}\), and \(x\) divisible by 37 needs \(10 - 2k \equiv 0\), so \(k = 5\) (the least positive value). \[ x = 1848\times 5 + 10 = 9250 = 37\times 250 \] \[ 9 + 2 + 5 + 0 = 16 \] The options 13, 15 and 17 do not match the digit sum of 9250.

Correct Answer : B

Multiplying two negatives gives a positive.

\[ -13a \times -2 = (13 \times 2)a = 26a \]

The variable \( a \) is carried through unchanged, so the answer keeps it - dropping it would leave the bare number 26.

Correct Answer : A

David sits between Binoy and Elias.

Number the six seats round the table 1 to 6. Put Atul at seat 1, so Binoy, opposite him, is at seat 4. Atul's two neighbours (seats 2 and 6) must be Elias and Chaaya, because each is said to sit next to Atul.

Chaaya sits between Atul and Firoz, and Firoz sits next to Binoy. So Chaaya is at seat 2 and Firoz at seat 3, beside Binoy at 4. That leaves Elias at seat 6 and David at seat 5, between Elias and Binoy, as the clue about Elias requires.

   Atul(1)

Elias(6)  Chaaya(2)

David(5)  Firoz(3)

   Binoy(4)

Firoz and Chaaya are on the other side of the table, and Binoy cannot sit between himself and Elias.

Correct answer: making predictions

The five steps run: identify the problem and the uncertainties; obtain information; make predictions about the future; choose among alternatives; and implement, evaluate and learn. Prediction is the third because it depends on the information gathered in the second and must precede the choice made in the fourth.

Correct Answer : E

Correct answer: has been

The subject he is third person singular, so the auxiliary is has, not have: he has been working. The tense itself is correctly chosen. An action that began in the past and continues into the present takes the present perfect continuous, and the marker here is for six years, a period of time. The pairing to remember is for with a duration - for six years, for a month - and since with a starting point: since 2019, since he joined. Had been would place the whole span in the past and imply he no longer works there. Is being and was being are passive continuous forms and cannot take an object the way this sentence requires. A useful check on agreement is to strip the sentence to its bones: he has, they have, she has, we have.

The unique network address is the Internet Protocol Address.

Every device connected to the Internet is identified by an IP address, either IPv4 (such as 192.168.1.1) or IPv6, which lets data packets be routed to it across networks.

A MAC address is a hardware address burnt into a network card and used only within a local network. A port number identifies a particular service or application on a device, not the device itself, and 'specific address' is not a technical term.

Beans fix nitrogen. Like all legumes they carry Rhizobium bacteria in root nodules, which convert atmospheric nitrogen into a form the plant can use.

This is why legumes are grown in rotation with cereals: they leave the soil richer in nitrogen than they found it.

The Earth is an oblate spheroid - a sphere flattened at the poles and bulging at the equator because of its rotation.

The equatorial diameter is about 12,756 km and the polar diameter about 12,714 km. 'Spheroid' alone is too loose, since a spheroid may equally be prolate, stretched along its axis.

The prerequisite for enforcing the directive principles is adequate resources.

Article 37 makes them fundamental to governance but not enforceable by any court, precisely because they require money the state may not have - free education, public health, social security. They are promises to be redeemed as the economy allows.
