The numbers of students speaking English and Hindi are in the ratio of 4:5. If the number of students speaking English increased by 35% and that speaking Hindi increased by 20% , what would be the new respective ratio?

Study the information given below and answer the questions based on it. A, B, C, D, E, F, G, H and I are nine people standing in 3 parallel rows facing north, in such a way that there is an equal distance between adjacent persons. Each row contains three positions. They speak different language Hindi, Marathi, Gujarati, English, Tamil, and Telugu. 1) I, D and G are standing in 3 different rows and they all speak a different language. 2) One who speaks Gujarati is immediate left of the one who speaks Marathi in Row-1. 3) There are 3 students who can speak English and all are standing in different rows. 4) H is standing in row-1 and speaks English. Also, he is at the right end. 5) G speaks neither Hindi nor English and speaks only that language which is not spoken by any other student. 6) One who speaks Tamil is in Row-2 and is diagonally opposite to the one who speaks Hindi and Telugu in Row-3. 7) One who Speaks Telugu in row-2 is in parallel to the students who speak Gujarati in row-1 and Hindi in row-3. 8) B is the only one who speaks Gujarati and is diagonally opposite to A. I is in the second row and D cannot speak English. 9) In Row-3 F is on the extreme right end. And He finds no difficulty to talk to E. Who is immediate neighbour of the one who speaks English in Row-2?

Unique enterprise is dealing in auto spare parts. With the expansion in business the enterprise found that the decisions are delayed and level of coordination is coming down. The CEO of the company called for a meeting of all the managers. Ayush, a newly appointed manager suggested that company should have its own internet so that all the employees can interact and pass important information to each other through internet. Even short meeting of different departments can be conducted through Video conferencing to take fast action. The CEO linked the idea and installed an internet connection for connecting all the employees on line. Which type of e-commerce is suggested by Mr Ayush? Explain.

It is possible to take a high quality photograph of a very fast moving object by illuminating the object for quite a small fraction of a second. You may have come across photographs of a bullet penetrating a banana or an apple in many text books or magazines. This is called 'stop action' photography because the fast moving object travels a very short distance during the time of illumination. Harold Edgerton, the inventor of stroboscope, was a pioneer of this kind of photography. A normal photographic plate works properly if it receives an energy of 4J during the exposure. To release this energy in a very small fraction of time, huge amount of power is required. Such huge power can not be generated directly from a battery because of its high internal resistance. To produce such power a capacitor is used. The time in which a capacitor discharges can be very short. Although, theoretically it would take a long time for a capacitor to discharge completely, it discharges almost completely in about 10 time constant. Consider the following situation A capacitor of 200muF storing 4J energy is made to discharge through a flash light in 2ms. This setup is used to take the picture of a bullet moving at a speed of 100m//s Assume that the flash light acts as a resistor and there is no other resistance in the circuit. What is the order of energy delivered to the flash light in 0.2 ms(approx).

If we use a lens of power 10 diopters, the lens to photographic plate distance is 15cm and the bullet moves perpendicular to the principal axis, what is the distance covered by bullet as seen on photographic plate.
