उत्तर
Z
Explanation:
First we will arrange the given information as shown below:
X has 2 chessboards + 1 record player
∴ Cost = 2 × 500 + 1 × 2000
= 3000 (at the beginning)
After transaction he has only 1 cycle and 1 chessboard
∴ Total Cost = 1000 + 500 = 1500
So, loss of X = 1500
Z has 1 cycle + 1 walkman
∴ Cost = 1000 + 700 = 1700 (at the beginning)
After transaction he has only 1 bat and 1 chessboard and 1 camera
∴ Total cost = 1 bat + 1 chessboard + 1 camera = 700 + 500 + 1500 = 2700
∴ Profit = 1000
Y has 3 bats
∴ Total cost = 3 × 700 = 2100 (at the beginning)
After transaction he has only 1 record player and 1 bat
∴ Total cost = 2000 + 700 = 2700
∴ Profit of Y = 600
W has 2 cameras
Cost = 5000 (at the beginning)
After transaction he has only 1 bat, 1 camera and 1 walkman
∴ Total cost = 1 bat + 1 camera + 1 Walkman
= 700 + 3500 + 700 = 4900
∴ Loss = 100
∴ Z became the highest gainer.

For the following question, read the given passage carefully and answer the question that follows.
`Religions, like camel caravans, seem to avoid mountain passes. Buddhism spread quickly south from Buddha's birth-place in southern Nepal across the flat Gangetic plain to Sri Lanka. But it took a millennium to reach China ... The religious belt stretched eventually to Mongolia and Japan, but in Afghanistan, Buddhism filled only a narrow belt that left pagans among the valleys to the east and west in Kailash and Ghor'.

Read the following passage and answer the question that follows:
As infrastructure investments (as a proportion of GDP) have fallen sharply over the twelfth five year plan period (2013-17), attempts to revive the investment cycle are welcome. However, considering that infrastructure investment over the past six years adds up to Rs 51.2 lakh crore, doubling this over the next six years is a tall order. These are not normal times. The economy has slowed down considerably. The financial system remains choked. Add to that an overleveraged corporate sector that is in no mood to invest, and achieving these targets looks increasingly difficult. And a broad-based pick-up in growth is unlikely in the near term. Reviving the investment cycle requires more than just ambitious targets.

Direction: Read the following passage and answer the question that follows:
With that deadline now a decade away, the world is set to miss most of the Sustainable Development Goals (SDGs). Just two of them — eliminating preventable deaths among newborns and under-fives and getting children into primary schools — are closest among all the goals of being achieved. By contrast, the goal to eliminate extreme poverty will not be met because some 430 million people are expected still to be living in such conditions in 2030. Targets to end hunger and to protect climate and biodiversity are completely off track. Whereas some of the richer countries are making a degree of progress in the SDGs overall, two-thirds of poorer ones are not expected to meet those that relate even to their most basic needs.
What can be concluded from the above?
Gayatri: Maharana Pratap was courageous no doubt, but his forces lost to the forces of Emperor Akbar the Great in the Battle of Haldighati. The king of a region such as Mewar and the Emperor of most of the Indian sub-continent at the time cannot both be eligible for the title, ‘the Great’, given the historical context.
Ranjini: Pratap never surrendered to Akbar in his lifetime despite Akbar sending several envoys to his great rival with the offer of making him a Mughal ally. Pratap’s defiance gave other Rajput rulers the courage to refuse alliance with Akbar. The victory in the Battle of Haldighati was a hollow victory for Akbar at best. Pratap’s forces were outnumbered by Akbar’s by far in the battle, but Pratap escaped with his life and subsequently recovered much of the territory lost in the battle. Maharana Pratap the Great received recognition of his greatness from none other than Emperor Akbar the Great. The latter is known to have wept on hearing the news of his rival’s death.
The patterns of reasoning in Gayatri’s argument closely resembles the pattern of reasoning in all of the following except?

Situation: Major X, an able officer in the Kapistan Army, failed to receive a promotion for eight years. Then he had been reassigned to a military supply depot in Khawalpindi, despite his university training in engineering and electronics,and his remarkably high-performance ratings from his commanding officers.X had never been an active member of any political party as a youth nor as an adult, yet neither had he given the party or his superiors any cause to doubth is absolute loyalty to Kapistan. X's brother-in-law had been a diplomat in theKapistan government until his death in 1971 in a plane crash on Koviet soil while he was working in the Kapistan Embassy in Kosco. X had always assumed that the mishap was indeed an accident, until his friend Y, a middle-level officer in the interior Ministry, broadly hinted that the plane crash had been an act of sabotage. Soon after the talk with Y, X visited his sister, the diplomat's widow, in her Kosco apartment. During the visit she asked X several questions that struck him as strange and inappropriate. As he was leaving her apartment, she asked X to wear her late husband's scarf and to return to his hotel by way of a certain park. Bewildered, but not wishing to offend his sister, X obeyed her odd instructions.
Result: Two months later, X received a promotion and was made Commander of the Kapistan missile division in Kahore.
For X, a missile base is a more highly prized assignment than a supply depot.
