Consider the following statements with reference to Jet stream. 1. The Jet Stream is a geostrophic wind. 2. There are two permanent jet streams – subtropical jets at mid-latitudes and polar front jets at lower latitudes. 3. Temperature also influences the velocity of the jet stream. The lower the difference in air temperature, the faster the jet stream. Which of the statements given above is/are NOT correct?
The fresh feed to an ammonia synthesis reactor contains nitrogen, hydrogen and 2.0 mole per cent inerts. The molar ratio of H2:N2 is 3:1. The product stream consists of pure ammonia. Since conversion in the reactor is only 15%, a recycle stream is used and in order to avoid build-up of inerts, a purge stream is withdrawn. The rate of purge stream is adjusted to keep inert concentration in the recycle stream at 8 mole per cent. For a fresh feed rate of 100 moles/hr. Note that recycle stream contains only nitrogen, hydrogen and inerts. The N2:H2 ratio of 1:3 is maintained in every process stream, and calculate the moles of nitrogen entering the reactor and in the recycle stream?

He retain 20% of the amount for taxi fare and buys 25 sanitizers and with the remaining amount he buys masks. Then find which of the following statement is/are true? a) No. of sanitizer are less than number of mask. b) Number of sanitizer are equal to the number of mask. c) Number of masks are less than number of sanitizers. Select the correct answer using the codes given below :   
Ashok buys some masks at 10 masks for ₹ 200. How should he sell the masks if he wants to realize a profit of 40%?
The following question, there are three statements I, II and III. Read the question carefully and mark your answer according to which statements(s) is/are sufficient to the answer the question. What is the Speed of the stream? Statement I: The distance between two points A and B is a km and the boat cover 90km along the stream in 5 hours. Statement II: The distance travelled along the stream is four times the total distance and that against the stream is three times the total distance Statement III: The total time taken against the stream is 10% more than that along the stream
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: A can do a piece of work in 10 days and B can do the same work in 15 days. They start working together and after 4 days, A left the work. Find in how many days the total work will be completed. Quantity B: P can do a piece of work in 15 days and Q can do the same work in 25 days. They start working together and after 5 days, Q left the work. Find in how many days the remaining work will gets completed.
‘P’ taken 16 days to finish a piece of work. ‘Q’ takes 24 days to finish the same piece of work.  'R' takes 48 days to finish the same piece of work. How many days will all three of them together take to finish the same piece of work?
K and L can complete a piece of work together in 15 days. K starts working and works for 10 days to complete two-fifth piece of work. L completes the remaining piece of work. The per-day wages paid to L  is Rs. 200. How much does L earn from completion of the remaining piece of work?
