96 men were engaged for a project of constructing a railway track of the length of 18 km in four weeks. After one week it was observed that the work of 4 km was completed. How many additional men should be engaged for timely completion of the project?
Answers
Answer:
Almost all rail operations are handled by the China State Railway Group Company, Limited, a state-owned company created in March 2013 (as China Railway Corporation) from dissolution of the Ministry of Railways. It was converted into a joint-stock company and placed under the control of the Ministry of Finance in June 2019.
China's railways are among the busiest in the world. In 2019, railways in China delivered 3.660 billion passenger trips, generating 1,470.66 billion passenger-kilometres and carried 4.389 billion tonnes of freight, generating 3,018 billion cargo tonne-kilometres.[1] Freight traffic turnover has increased more than fivefold over the period 1980-2013 and passenger traffic turnover has increased more than sevenfold over the same period.[7] Driven by need to increase freight capacity, the railway network has expanded with the country budgeting $130.4 billion for railway investment in 2014, and has a long-term plan to expand the network to 274,000 km (170,000 mi) by 2050. China built 9,000 km of new railway in 2015.
