Correct Answer : B

Given \(2b = a+c\), \(c^2=bd\), and \(c,d,e\) are in H.P. so \(d = \frac{2ce}{c+e}\). From \(c^2=bd\), we have \(d=c^2/b\). So \(c^2/b = \frac{2ce}{c+e} \Rightarrow c/b = \frac{2e}{c+e} \Rightarrow c(c+e) = 2be\). From the first condition, \(b=(a+c)/2\). Substitute this: \(c(c+e)=2(\frac{a+c}{2})e \Rightarrow c^2+ce = (a+c)e = ae+ce \Rightarrow c^2 = ae\). This is the condition for a, c, e to be in G.P.

Correct Answer : C

The jogger runs the same way, so the train closes at the difference of the speeds.

\[ \text{relative speed} = 45 - 9 = 36 \text{ kmph} = 36 \times \frac{5}{18} = 10 \text{ m/s} \]

To pass him completely, the train must cover the 240 m gap plus its own 120 m:

\[ t = \frac{240 + 120}{10} = 36 \text{ seconds} \]

Covering only the 240 m gap brings the engine level with the jogger, not the whole train past him.

Students let us understand the Logic behind this Question and let’s understand how to solve it. When we see the each step, then we can find that there is both number and words are arranged in each step.
1) For words arrangement- Words are arranged according to ascending order given in English dictionary. In first step the words which come first according to English dictionary arranged first to extreme right. And in second step next word according to English dictionary are arranged to extreme left.
And this process is continued in further step.
2) For number arrangement- Number are arranged according to ascending order. There are three odd number and three even numbers. In first three step odd number are arranged in ascending order first to extreme left end then to extreme right. And in last three step even number are arranged in ascending order. (Each odd number is added by 1 while they are arranged and each even number is subtracted by 1 while they are arranged).

Correct Answer : A

Correct answer: 33

Every gap is the same: the differences run 7, 7, 7, so the common difference is 7. Applying it once more to the final term, 26 + 7 gives 33. As a check, subtracting 7 from the answer returns 26, the term before it, and repeating that recovers the whole series. A constant difference is the first thing to test on any number series, because it is the commonest rule and takes only two subtractions to rule in or out.

The correct matching is a-4, b-3, c-2, d-1.

Keenan Stadium is the Tata Steel cricket ground at Jamshedpur (a-4). The MECON Stadium is in Ranchi, at the MECON township in Doranda (b-3). The Paramveer Albert Ekka Stadium is named after the Param Vir Chakra awardee from Gumla district and stands in Gumla (c-2), which leaves the Indoor Stadium for Dumka (d-1).

Once Keenan Stadium is placed in Jamshedpur and the MECON Stadium in Ranchi, only one option remains: the others put Keenan Stadium in Dumka or Ranchi.

Correct Answer : C

Correct answer: The northern hemisphere

The northern hemisphere holds roughly two thirds of the world’s land, and is about 60 per cent ocean; the southern is around 81 per cent ocean. Nearly 90 per cent of the world’s people live north of the equator. This asymmetry has a real climatic effect. Land heats and cools much faster than water, so the northern hemisphere has a larger annual temperature range and more pronounced continental climates, while the southern is moderated by its vast oceans. It is also why the thermal equator - the belt of highest temperature - sits north of the geographic one for most of the year. The monsoon system depends on the same contrast: the huge Asian landmass heating in summer draws air from the Indian Ocean. The eastern hemisphere does hold more land than the western, but that division is a separate one, made by the Prime Meridian rather than the equator.

Correct Answer : D

Correct answer: The alignment of mineral crystals under directed pressure

Foliation arises when metamorphism occurs under pressure that is greater in one direction than another. Platy minerals such as mica recrystallise with their flat faces perpendicular to the maximum stress, so the rock develops parallel layers and splits easily along them. It produces a recognisable sequence of increasing metamorphic grade: shale becomes slate, then phyllite, then schist, then gneiss, the crystals growing coarser and the banding more pronounced at each step. Slate’s ability to split into thin sheets - its cleavage - is what makes it a roofing material. Rocks metamorphosed under uniform pressure, or made of minerals with no platy habit, come out non-foliated instead: limestone becomes marble and sandstone becomes quartzite, both massive rather than banded. The layers of a sedimentary rock look similar but are bedding, formed by deposition, and they record the surface on which the sediment settled rather than the direction of later stress.

These are the jet streams.

They are narrow ribbons of wind near the tropopause, 9 to 12 km up, blowing west to east at 100 to 400 km/h. The subtropical jet's seasonal shift north of the Himalayas triggers the burst of the Indian monsoon, and aircraft ride them to save fuel.

The next-generation supersonic trainer is the HLFT-42.

HAL unveiled a full-scale model of the HLFT-42 (Hindustan Lead-in Fighter Trainer) at Aero India in February 2023. It is designed as a supersonic lead-in fighter trainer to prepare pilots for frontline combat aircraft.

The IJT (Intermediate Jet Trainer) is subsonic. The LCA Tejas is a light combat aircraft (option D names the same aircraft), not the new trainer.
