By what least number 21, 600 should be multiplied to make it a perfect...
It is a simple question, you can even solve it without using pen and paper. split 21600 in the multiplication of prime numbers
as it is 2(cube)*3(cube)*100 so you need to multiply it by 10 then it will be a perfect cube of (2*3*10)cube
or 60cube=216000

21600=8*27*100 I hope you can understand more clear from it.

The following table represents the records in the last 5 series and fitness statistics of 11 Indian Cricket Team players A to K.The Speed, Strength and Agility are measured in certain indices, and the values mentioned are out of a 0 to 100 scale. The Fitness Index is calculated as followsFitness Index = 0.4 x Speed + 0.3 x Strength + 0.3 x AgilityThe following table represents the records in the last IPL season and the fitness index for 8 players, P to W, who have played in the IPL but are yet to debut for the Indian Cricket Team.Based on the information, given above, answer the questions that follow.Q. For the upcoming series vs England, the Squad Selection Committee selects players and assigns them jersey numbers in the following way:First, it starts with the players who have already played for India. The players are ranked as per their Fitness Index ( highest fitness index is ranked 1). Then the first players selection process starts, he must meet at least one of the below three criteria: 1) His batting average must be among top 6 batting averages of all players who have played for India 2) The number of wickets taken by him should be among the top 3 of all players who have played for India. 3) His number of catches/runouts should be the highest among all players who have played for India. If a player is selected, he is assigned a jersey number 1. Similarly, it continues for other players, and the nth player to be selected is given a jersey number n.After the selection round of A to K is done, the selection of P to W begins. The players are ranked as per their Fitness Index ( highest fitness index is ranked 1). Then the first players selection process starts, he must meet at least one of the below two criteria: 1) His total runs scored must be among top 4 runs scored of all players from P to W 2) The number of wickets taken by him should be among the top 3 of all players from P to W. If after meeting all these criteria, he is selected, he is assigned a jersey number which immediately succeeds the last jersey number from A to K. So, if K is the last person to be picked from A to K, and he is assigned a jersey number of 8, the first one from to be selected from P to W is given a jersey number 9. Also, players successively selected are given successive jersey numbers.If the rank of 2 players based on their Fitness Index is the same, we rank them in alphabetical order of their names, that is if both A and D have the 4th rank A is ranked 4 and D is ranked 5.How many players are selected into the squad for the upcoming series?

Direction: Read the following passage carefully and answer the question that follow.The long, anxious, and frustrating wait by people outside banks and ATMs across the country over the last five days is an inevitable consequence of the decision to demonetise notes of Rs.500 and Rs.1,000. When 86 per cent of the value of notes in circulation turns suddenly invalid, as it did with Prime Minister Modi’s ‘surgical strike’ last week, a certain degree of disruption and pain is unavoidable. But the question is whether this “chaos” could have been anticipated and managed better than it has been.Replacement of the demonetised notes is a time-consuming exercise that requires planning of the highest order. The experience of the last few days shows that preparation was lacking and the “transition” could have been handled much better. ATMs are running out of cash quickly while banks are dispensing more of the Rs.2,000 notes than those of lower denominations. What use is a high-value note if there is not enough smaller currency to make an exchange? Of course, it was never an easy task for the Reserve Bank of India and the Centre to strike the right balance between secrecy and storing adequate quantity of notes for quick distribution. All the same, there are at least a couple of issues that could have been addressed differently.The new Rs.500 notes that hit the market on Monday could have been released immediately after the announcement last week. Putting out new Rs.500 notes along the Rs.2,000 notes would have placed much less strain on those of the Rs.100 denomination, which are anyway in short supply. Second, it appears that officials woke up a little late to the issue of recalibrating ATMs. At least a day, if not more, was lost as banks realised the ATMs would not be able to dispense the new notes. The communication with the public, who were in a state of panic, could have been better, too.Thankfully, the Centre has woken up to “ease” the pressure on the system by increasing withdrawal limits, allowing for petroleum outlets and hospitals to accept the old series of notes until November 24 and pushing more cash through post offices. The worst-affected are people in rural areas and villages where cash is king and the banking system’s penetration is poor. The decision to relax cash-holding limits for banking correspondents, the crucial link between banks and villages, to Rs.50,000 and allowing them to replenish multiple times a day should help in faster distribution. This ought to have been done much earlier. The cash crunch of the last few days is certain to have an adverse impact on consumption spending, especially in the rural areas, with the resultant effect on the economy in the third quarter.Q. Why do you think that the replacement of the demonetised notes is a time-consuming exercise?
