प्र:

What, one wonders, is the lowest common denominator of Indian culture today? The attractive Hema Malini ? The songs of Vinidh Barati? The attractive Hema Malini? The sons of Vinidh Barati? .
Or the mouth-watering Masala Dosa? Delectable as these may be, each yield pride of place to that false (?) symbol of a new era-the synthetic fibre. In less than twenty years the nylon sari and the terylene shirt have swept the countryside, penetrated to the farthest corners of the land and persuaded every common man, woman and child that the key to success in the present day world lie in artificial fibers: glass nylon, crepe nylon, tery mixes, polyesters and what have you. More than the bicycles, the wristwatch or the transistor radio, synthetic clothes have come to represent the first step away form the village square. The village lass treasures the flashy nylon sari in her trousseau most delay; the village youth gets a great kick out of his cheap terrycot shirt and trousers, the nearest he can approximate to the expensive synthetic sported by his wealthy citybred contemporaries. And the Neo-rich craze for ‘phoren’ is nowhere more apparent than in the price that people will pay for smuggled, stolen, begged borrowed second hand or thrown away synthetics. Alas, even the uniformity of nylon.

व्याख्या :

In business, outsourcing is an agreement in which one company contracts its own internal activity to different company. It involves the contracting out of a business process (e.g. payroll processing, claims processing) and operational, and/or non-core functions (e.g. manufacturing, facility management, call center support) to another party (see also business process outsourcing).   A company moves some of its jobs to another country and employing workers in other countries to save on labor costs best describes the practice of outsourcing.

उत्तर : 2. "420 m"
व्याख्या :

Answer: B) 420 m Explanation: Let the length of the stationary train Y be LY Given that length of train X, LX = 300 m Let the speed of Train X be V. Since the train X crosses train Y and a pole in 60 seconds and 25 seconds respectively. => 300/V = 25 ---> ( 1 ) (300 + LY) / V = 60 ---> ( 2 ) From (1) V = 300/25 = 12 m/sec. From (2) (300 + LY)/12 = 60 => 300 + LY = 60 (12) = 720 => LY = 720 - 300 = 420 m Length of the stationary train = 420 m
