A statement is given below in the question followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: Jet Airways has defaulted on salary payments again. The cash-strapped airline on Wednesday sought over 10 more days from its employees to pay balance 25 per cent of their salaries for August. Jet Airways had paid 50 per cent of August salaries to its employees on September 11 and the rest was to be paid on Wednesday. But it could pay only half of the balance amount.  Courses of action: I. The cash-strapped airline, which is struggling to meet its cost of operations, had earlier attempted to cut salaries of its employees, but the move was met with stiff resistance that forced it to defer the plan.  II. Jet Airways will today remit half of the second installment of pending emoluments of its pilots, AMEs and senior management for August 2018. III. While the management regrets the attendant inconvenience, it also appreciates the continued support and understanding of its employees.

Air samples collected from the intake and the return gates of a retreating longwall face show methane concentration values of 0.1% and 0.8% respectively. The production from the longwall face is 2000 tonne/day and the air quantity circulating the face is 15 m3/s. The rate of methane emission in m3 per tonne of coal produced is
The failure data analysis of a longwall mining system consisting of thre major subsystems revealed that the failure rate of shearer, face conveyor any stage loader are 0.15/ hour, 0.2/ hour and 0.1/ hour respectively. If all the subsystems must be running for a satisfactory system operation, the reliability of the longwall system for a period of 4 hours is
Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it. The first working steam­ powered vehicle was designed and most likely built by Ferdinand Verbies, a Flemish member of a Jesuit mission in China around 1672. It was a 65 cm long scale­ model toy for the Chinese Emperor, that was unable to carry a driver or a passenger. It is not known if Verbiest's model was ever built. Nicolas- Joseph Cugnot is widely credited with building the first full­ scale, self ­propelled mechanical vehicle or automobile in about 1769; he also created a steam­ powered tricycle. He constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts. His inventions were however handicapped by problems of water supply and maintaining steam pressure. In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam ­powered road vehicle. It was unable to maintain sufficient steam pressure for long periods. Sentiment against steam ­powered road vehicles led to the Locomotive Acts of 1865. In 1807 Nicephore Niepce and his brother Claude probably created the world's first internal combustion engine which they called Pyreolophore. The first full­scale, working steam ­powered tricycle was built by:
