The pie chart given below shows the fuel consumption by five vehicles V1, V2, V3, V4 and V5. In a month total fuel consumption by all five vehicles is 720 litre. Fuel consumption of a particular vehicle is shown in terms of degree with respect to the total fuel consumption by all these five vehicles. J1 = Difference between the fuel consumption of V4 and V5. J2 = Difference between the fuel consumption of V1 and V2. What is the value of J2 – J1?
Read the given statements carefully and answer the question. The main reasons for vehicles crawling on city roads during peak hours are increasing number of private vehicles and double parking which is a very common sight. A survey reveals that vehicles move on an average at 20 kmph during peak hours. Which of the following is true according to the given statement? A. Vehicles move at 20 kmph during 5 pm to 9 pm. B. Double parking is not a violation of traffic rules in the city. C. The number of private vehicles have gone up. D. The number of Government vehicles remain the same.
Study the line graph and answer the question that follows. The line graph represents the number of vehicles (in thousands) manufactured by two automobile companies A and B over the years from 2010 to 2015. The X-axis represents the years and the Y-axis represents number of vehicles in thousands. (The data shown here is only for mathematical exercise. They do not represent the actual figures of the country.) Company B is projecting an increase in the number of vehicles to be manufactured in 2016 by 70% with respect to its average number of vehicles from 2010 to 2015. What should be the approximate percentage increase in the number of vehicles (in thousands) to be manufactured by Company A in 2016 with respect to the number of vehicles in 2015, so that it is at par with Company B?
Consider a set U of 23 different compounds in a Chemistry lab. There is a subset S of U of 9  compounds, each of which reacts with exactly 3 compounds of U. Consider the following statements:  I. Each compound in U\S reacts with an odd number of compounds. II. At least one compound in U\S reacts with an odd number of compounds. III. Each compound in U\S reacts with an even number of compounds. Which one of the above statements is ALWAYS TRUE?
Which of the following statement(s) is/are CORRECT? I. Carbon compounds linked by only single bond are called saturated compounds. II. Carbon compounds having double or triple bonds are called unsaturated compounds. III. Saturated carbon compounds are more reactive than unsaturated carbon compounds.
In the question below, are given a statement 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 suggested courses of action logically follow(s) for pursuing. Statement: Soon you would not need to carry original copies of all vehicle papers like driving licence, vehicle registration certificate, insurance, pollution certificate or the permits issued to commercial vehicles with you. According to a ToI report, the Centre plans to amend Motor Vehicles Rules to make it legal for any citizen to carry digital vehicle documents and simultaneously making it compulsory for traffic police to accept digital version of documents. This means that you would not have to carry physical papers in your vehicle as digital copies of the certificates would be valid.  Courses of action: I. The ministry has proposed installation of FASTags on the front windscreens. FASTag is a device that uses radio frequency identification (RFID) technology for making toll payments directly from the user account.  II. To avail the facility, one has to store all the vehicle documents on the government's cloud-based service DigiLocker and when asked he/she can simply display the stored certificates on a smartphone or any other digital devices. These digital copies can be shared with other departments as identity and address proof.  III. The government has increased the maximum load carrying capacity of heavy vehicles, including trucks, by 20-25 per cent besides scrapping the mandatory annual renewal of fitness certificates for freight carriers. Fitness certificates for trucks would now be renewed in every two years not annually.  Which of the following course/courses of action can be said to be said to be a rudimentary course/courses of action?
A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
Study the line graph and answer the question that follows The line graph reprensents the number of vehicles (in thousands) manufactured by two automobile companies A and B over the years from 2010. The X -axis represents the years and Y -axis represents of vehicles in thousands. (The data shown here is only for mathematical exercise. They do not represent the actual figures of the country) If there was an increase of 24% in the average number of vehicles (in thousands) manufactured by company B during 2011 to 2014) with respect to number of vehicles manufacured by company A in 2009. then how many vehicles (in thousands) did company A manufacture in 2009?
Consider the following statements regarding hydrogen fuel cell. 1. Fuel cell electric vehicles (FCEV) uses hydrogen, and an oxidant to create electricity by an electrochemical process. 2. Like a battery-electricity vehicle, fuel cell electric vehicles (FCEV) can also store energy. 3. Hydrogen fuel cells produce much smaller quantities of greenhouse gases. Which of the statements given above is/are correct?
With reference to 'fuel cells' in which hydrogen-rich fuel and oxygen are used to generate electricity, consider the following statements: 1. If pure hydrogen is used as a fuel, the fuel cell emits heat and water as by-products. 2. Fuel cells can be used for powering buildings and not for small devices like laptop computers. 3. Fuel cells produce electricity in the form of Alternating Current (AC) Which of the statements given above is/are correct?
