Of three positive numbers, the ratio of the first and second numbers is 3:4 & that of the second and third numbers is 5:6. The product of the second and third numbers is 4320. What is the sum of three numbers?

Name the first Indian who got Nobel Prize in physics.

A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example 'K' can be represented by 01, 34, etc... and 'P' can be represented by 65, 99, etc... Similarly, you have to identify the set for the word "BLAND".

The average of 17 results is 60. If the average of first 9 results is 57 and that of the last 9 results is 65, then what will be the value of 9th result?

In each below is given a statement followed by three conclusions numbered I, II and III. You have to assume everything in the statement to be true, then consider the two conclusions together and decide which of them logically follows beyond a reasonable doubt from the information given in the statement Give answer:

Statement:

For the first time India will invite heads of ten Asian nations for the Republic day 2018 celebrations. ASEAN is the association of south-east Asian nations. Its members are Vietnam, Laos, Philippines, Singapore, Thailand, Indonesia, Cambodia, Brunei, Malaysia and Myanmar.

Which of the following can be inferred from the given statement?

Conclusions:
(i) Republic day 2018 will be the first event ever where so many leaders will together will be the chief guests at the parade which would showcase India’s Military might.
(ii) India is the only country among southeast Asian nations which celebrates Republic Day.
(iii) India and ASEAN are actively engaged in a comprehensive economic partnership, which is expected to emerge as the largest regional trading arrangement.

In the question given below, three paragraphs are given, which are jumbled. Find the correct sequence of these paragraphs so that they form a meaningful passage.
A. Climate change is warming the ocean, but it’s warming land faster and that’s really bad news for air quality all over the world, says a new University of California, Riverside study. The study, published February 4 in Nature Climate Change, shows that the contrast in warming between the continents and sea, called the land-sea warming contrast, drives an increased concentration of aerosols in the atmosphere that cause air pollution. Aerosols affect the climate system, including disturbances to the water cycle, as well as human health. They also cause smog and other kinds of air pollution that can lead to health problems for people, animals, and plants.
B. To determine this, the researchers ran simulations of climate change under two scenarios. The first assumed a business-as-usual warming model, in which warming proceeds at a constant, upward rate. The second model probed a scenario in which the land warmed less than expected. In the business-as-usual scenario, enhanced land warming increased continental aridity and, subsequently, the concentration of aerosols that leads to more air pollution.
C. A robust response to an increase in greenhouse gases is that the land is going to warm faster than the ocean. This enhanced land warming is also associated with increased continental
aridity. The increase in aridity leads to decreased low cloud cover and less rain, which is the main way that aerosols are removed from the atmosphere.
