**How to concentrate for 3 hours during cat mock?**

Hi Harish,

One of the many reasons to take mock CATs is to get yourself accustomed to concentrate for 3 hours. It's just the beginning of the mock season so if you are not able to concentrate, don't worry. Just keep taking mocks and you will get used to it. Another thing that you can try is to take sectional tests. Instead of taking a full length mock, take a sectional test, take rest for 15 minutes then start the second section, then take rest for another 15 minutes and take the third section. As you progress, keep reducing the rest time that you take between sections. It will help you improve your concentration

Thanks

**A raindrop consists of 75% water and the rest is dust. However, by the time it reaches the surface of Earth, it is left with 70% water as 2 ml water evaporates on the way. Find the original volume of the raindrop.**

Before, The volume was V and the amount of water was 0.75V

After 2ml of water was lost, the volume became V-2 and the amount of water became 0.7(V-2).

This results in the equation 0.7(V-2) = 0.75V-2. Solving this will give you 12ml.

**Ashish is given Rs. 158 in one-rupee denominations. He has been asked to allocate them into a number of bags such that any amount required between Re 1 and Rs. 158 can be given by handing out a certain number of bags without opening them. What is the minimum number of bags required? A 11 B 12 C 13 D None of these Explanation The possible arrangements are 1,multiples of 2 ,remaining. So we have 1+2+4+8+16+32+64+31 = 158. Hence minimum no. of bags required is 8. why the bag of 31 ?**

A bag of 31 is needed to cover for the values above 127. 1+2+4...+64 = 127, so if somebody asks you for say 155 coins, How would you give him?

64+32+31+16+8+4. So we need a bag of 31 to cover the values between 127 and 158.

Thanks
