In a liquid-liquid extraction, 10 kg of a solution containing 2 kg of solute C and 8 kg of solvent A is brought into contact with 10 kg of solvent B. Solvent A and B are completely immiscible in each other whereas solute C is soluble in both the solvents. The extraction process attains equilibrium. The equilibrium relationship between the two phases is Y* = 0.9X, where Y* is the kg of C/kg of B and X is kg of C/kg of A. Choose the correct answer.

In the question below, a statement is given, 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 course of action logically follow (s) for pursuing. Statement: Led by a strong response to its first super sports utility vehicle Urus, Italian sports car maker Lamborghini is likely to more than double its volumes in India by the end of 2019, a year ahead of its plan, and cross the milestone of 50-60 vehicles per annum. The company, which began deliveries for Urus in India in September, said the vehicle is already booked for the coming six-nine months in India much like the global markets, and it will help Lamborghini get new. customers into its fold. Courses of action: I. The company is planning not to increase the price of its vehicle despite significant rupee depreciation and wants to protect the attractive price of Urus for prospective buyers.  II. The super sports utility vehicle will drive volumes, super sports cars such as Huracan and Aventador will grow by 8-10%. The company feels an 8-10% growth in the segment is a realistic expectation in spite of the challenges.  III. More than 68% of Urus buyers are first-time Lamborghini buyers and makers are sure that this will have a positive rub-off effect on the super sports car segment too.
By studying all following options, select a pair that uses most closely similar reasoning. a. Researchers have looked at the communication between different animals and found that meerkats have a series of alerts and calls that fail into two categories, greetings and alarms. Since we can be sure that this meerkat is not calling as a greeting, we must accept that he is attempting to raise the alarm. b. Farmers must choose between using organic or non-organic fertilisers on their land. Organic fertilisers can produce a lower crop yield and farmers may find it difficult to change to organic methods if they have been using non-organic methods for some time. Farmers should, therefore, consider the longer-term impacts of their decisions. c. Either young persons are getting cleverer each year or examinations are becoming easier for students to pass. Since there is very little evidence from IQ testing and other supposed benchmarks that young persons are more intelligent now than in the past, we must conclude that the examination system is easier for students today than it was in the past. d. Closed wood burning chulhas are a better way to cook your food than open fire chulhas. Closed wood burning chulhas are highly efficient, whereas the open fire of open fire chulhas loses a great deal of heat in the air. More people should, therefore, use closed wood burning chulhas in their homes.

The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the mole fraction of the solvent, if the decrease in vapor pressure of the solvent is required to be 20 mm Hg.?
Which of the following statements are comes for Network Critical Path? 1. The path of critical activities, which links the start and end events is critical path 2. It is the path of activities having zero float 3. It is the path of events having zero slack 4. The sum of the duration of the critical activities along a critical path gives the duration of the Project
