Dr. Xman is diluting concentrated HCl acid by mixing water in it. The quantity of mixture is 32 l. The ratio of concentrated HCl to water is 7 ∶ 1. If 3 l of water is added to the mixture, the ratio of HCl to water changes to new ratio. If he want to change back the new ratio to the original value, how much concentrated HCl is to be added?

P. 0.2% yield strength of a material implies 0.2% of the yield strength.
Q. Von-Misses yield criterion implies that yielding occurs when the distortion energy reaches a critical value.

Louis Pasteur mixes two acids HCL and HNO3 in the ratio 7 ∶ 5 and filled it in a container. When 9 liters of solution is taken out and the can is filled with HNO3, the ratio of HCL and HNO3 becomes 7 ∶ 9. How many liters of HCL was contained by the container initially?
P, Q, R, Sand T are five crops that Babu grows. T is fast growing and more water demanding than R which gives more yield than T. P gives more yield than R and grows faster than Q. Q is more water demanding than T but is second lowest yielder, S is the slowest growing and least water demanding of all crops but gives highest yield. R is more water demanding and grows faster than P. Select the crop or crops that has/ have as many as crops that are more water demanding and as many as crops that give less yield than it. 
If the specimen is deformed plastically beyond the yield stress in one direction, e.g., tension and then after unloading it is loaded in the opposite direction, e.g., compression, it is found that the yield stress is less than the original yield stress. This dependence of yield stress on direction loading is called ____________
