A Double-ended queue supports operations such as adding and removing items from both the sides of the queue. They support four operations like addFront(adding item to top of the queue), addRear(adding item to the bottom of the queue), removeFront(removing item from the top of the queue) and removeRear(removing item from the bottom of the queue). You are given only stacks to implement this data structure. You can implement only push and pop operations. What are the total number of stacks required for this operation?(you can reuse the stack)
A suit, a trouser, and a shirt are to be stitched from a cloth. The cloth required for the suit is the average of cloth required for trousers and shirt. The length of the cloth for suit is 1.5 times the cloth required for the shirt. The length of cloth required for shirt is 5 times the even prime number. Which of the following is/are correct? A. Cloth required for trousers is 20 m B. Average length of cloth required for all the dresses = Cloth required for suit C. Initially, the cloth was 45 m D. Cloth required for shirt is 15 m

How is permaculture farming different from conventional chemical farming? 1. Permaculture farming discourages monocultural practices but in conventional chemical farming, monoculture practices are predominant. 2. Conventional chemical farming can cause an increase in soil salinity but the occurrence of such phenomenon is not observed in permaculture farming. 3. Conventional chemical farming is easily possible in semi-arid regions but permaculture farming is not so easily possible in such regions. 4. Practice of mulching is very important in permaculture farming but not necessarily so conventional chemical farming Select the correct answer using the code given below.  
The chemical equivalent of MgSO4 salt is ____________
If a sample water has not supplied any heat and having impurities as follows: Mg(HCO3)2=50 mg of CaCO3, MgSO4 = 100mg of CaCO3, CaCl2=200mg of CaCO3, Ca(NO3)2=100mg of CaCO3. Calculate the lime required for treatment of 10000 litres of water.
Chemical mixtures X consist of chemicals A and B in ratio of 1 : 3, Chemical Y consist of chemicals A and B in ratio of 3 : 2.

Product X is produced by mixing chemical A and chemical B in the ratio of 5 : 4. Chemical A is prepared by mixing two raw materials, P and Q, in the ratio of 1 : 3. Chemical B is prepared by mixing raw materials, Q and R, in the ratio of 2 : 1. Then the final mixture is prepared by mixing 8640 units of product X with water. If the concentration of the raw material Q in the final mixture is 50%, how much water had been added to product X?
