65 − 37 = 28. Adding the same difference to 51 gives 51 + 28 = 79. (The pair can also be read as 37 + 28 = 65, so 51 + 28 = 79.)

The law of inertia is Newton's first law of motion: a body stays at rest or in uniform motion in a straight line unless an external force acts on it. Isaac Newton stated it in the Principia (1687), building on Galileo's work.

Baseball is regarded as the national sport (the 'national pastime') of the USA. American football and basketball are also popular, but baseball is the traditional answer.

A car runs on petrol as its fuel; a (steam) locomotive runs on coal. So the pair is Locomotive : Coal.

The order only says construction is banned until the municipal body finds an effective way to manage waste.

Only English = 100 − (20 + 30 + 15 + 10 + 5) = 20. Students liking only one language = 20 + 30 + 15 + 20 = 85.

Net neutrality is the principle that internet providers must treat all data equally, without blocking, throttling or charging differently for different content. It is therefore about differential pricing of internet services: TRAI's February 2016 regulation, upholding net neutrality, prohibited such discriminatory tariffs. Of the options, D names the issue net neutrality deals with.

twitter.com, facebook.com and youtube.com are website addresses (domain names). WhatsApp is written as an app name, not a web domain, so it is the odd one.

Let the sides be l and b. l + b = 13 and l² + b² = 11² = 121. Then 2lb = (l + b)² − (l² + b²) = 169 − 121 = 48, so the area lb = 24 sq cm.

x² − y² = (x − y)(x + y). Dividing by (x − y) leaves x + y.

Replacing the symbols: 12 + 16 − 4 × 4 ÷ 2 becomes 12 − 16 ÷ 4 + 4 × 2. By BODMAS: 16 ÷ 4 = 4 and 4 × 2 = 8, so 12 − 4 + 8 = 16.

Lu takes the apple and Fu the mango. Moo takes neither banana nor orange, so Moo takes the plum. Ku takes neither plum nor banana, so Ku takes the orange. That leaves the banana for Hu.

With Lu (apple), Fu (mango) and Moo (plum) fixed, Ku cannot take the plum or banana, so Ku takes the orange.

The final allocation is Lu – apple, Fu – mango, Moo – plum, Ku – orange, Hu – banana. Only 'Moo – Plum' is correct.

Kepler's first law: every planet moves in an elliptical orbit with the Sun at one of the two foci.

cos 0° = 1, sin 30° = 1/2 and cosec 45° = √2. So 5(1) − 4(1/4) + 6(2) = 5 − 1 + 12 = 16.

ISI is Pakistan's Inter-Services Intelligence agency. (In India, ISI also stands for the Indian Standards Institution mark, but of these options only Inter-Services Intelligence is a real expansion.)

Tawang Monastery (Galden Namgey Lhatse), the largest Buddhist monastery in India, is in Tawang district of Arunachal Pradesh.

723 and 728 share 'feel good', so 7 and 2 stand for feel and good; then we = 3 and factor = 8. In 9731, 7 = feel and 3 = we, so definitely and so are 9 and 1 in some order. Which is which cannot be determined.

TRAI's call-drop rule (October 2015) required operators to credit Re 1 per dropped call, up to three a day, to the consumer on their own, without the consumer claiming it. So the compensation is paid automatically by the operator. B ignores the three-a-day cap.
