A growing world population has caused growing concerns about increasing famine. The population in 2000 was 6 billion. Ten years later the population was 7 billion. There were also more people affected by famines in 2010 than in 2000. Furthermore, in each year from 2000 to 2010, when the world's population increased, so did the number of those affected by famine.
Based on the information given, which of the following is true?
A tunnel of length 360 m is to be constructed. As per the plan, the team has to complete the tunnelling within a specified period of time. For the first four days, the tunnelling was done according to the plan. However, it was found that the resources were being underutilized. It was then decided that the rate of tunnelling should be increased and then they started tunnelling 15 m more than their everyday plan. Therefore, a day before the planned date they had tunnelled to a length of 380 m. How many meters of tunnelling was planned for each day?
