N.B.: a*b means 'a' no. of notes each of value 'b'\n\n100 = 100\n100 = 50 + 2*20 + 10\n100 = 50 + 2*20 + 5 + 2*2 + 1\n100 = 50 + 2*20 + 10*1\n100 = 50 + 2*20 + 5*2\n100 = 50 + 2*20 + 2*5\n100 = 50 + 2*20 + 3*2 + 4*1\nand so on.

This sounds like a homework question and I think you need to figure it out yourself -- this is how you learn!  What I can tell you as a hint is to start at the beginning and then add or subtract the numbers to change the balance, and break it down so you do it is step by step.

2x^2 + 5x + 20x + 50\n2x^2 + 25x + 50

The trick is how the question is asked. However if you look at it objectively, the three men spent a total of Rs. 270 which includes the Rs. 20 that the waiter kept for himself. So the total is 250 (restaurant bill) + 20 (waiter) + 30 (money that they got back). \nThe question has been asked in such a way so as to trick the reader. You don't have to add the 20 to 270 because the 20 is already included in 270.

Actually the Hindus started using the decimal numbering system, 0 to 9, 1500 years ago.  after 9 you add 1 infront to make 10, 12, 13, etc.

No, but you can work it out on paper. I know because I did it once. You have five letters, so there should be 25 combinations, Of course, as two letters are the same that would make it 20. I think. Just give it a go. It's always more fun to work these tings out yourself.

100! = 100*99*98...3*2*1\n\nSources of zeroes are multiples of five and multiples of 10:\n10, 20, 30, ... (10 to 90 and 100, 11 zeroes)\n5*2, 25*2, ... (5, 15, 25... 95, will make 10 zeroes)\n25, 50, 75 (another 3 zeroes)\nSo I guess it should be total 24 zeroes.

OOHHH! OHHH!!! I KNOW THE ANSWER TO THIS!!! ok, there is an equation for this, it's    n(n-1)/2.\n\nSo, if there are 100 "techies" then put 100 into the equation.\n\n100(100-1)/2------the equation\n100(99)/2------simplified\n9900/2------- 100*99\n4950-----THE ANSWER!!!\n\nSo, there would be 4950 cards exchanged!\n\nTHIS IS THE ANSWER, I PROMISE YOU!

1)    let x be the number of Rs 500\n       so, 200 - x is the number of Rs 200 (because the number of prizes must sum up to 200 to be distributed amongst the 200 persons)\n\n       Rs 500*(number of Rs 500) + Rs 200*(number of Rs 200) = Rs 50000\n      (Rs 500)(x) + (Rs 200)(200-x) = Rs 50000\n       500x + 40000 - 200x = 50000    (just distributed Rs 200)\n       500x - 200x = 50000 - 40000    (40000 was subtracted from both sides of the equation)\n       300x = 10000\n            x = 33.3333 <--- number of Rs 500\n 200 - x = 166.666667 <--- number of Rs 200\nthe answers must be whole numbers... but if you will round it off to the nearest unit digit, there will only be a total of Rs 49900. so, it is not possible for 200 Rs 50000 to exist consisting only of either Rs 500 or Rs 200.\n\n2)   let x be the worth of Bryan's property\n    (Son's share) + (Daughter's share) + (Wife's share) = (total worth of Bryan's property)\n      (1/5)(x) + (1/5)(x) + Rs 288000 = x\n       (2/5)(x) + Rs 288000 = x\n        Rs 288000 = x - (2/5)(x)\n         Rs 288000 = (3/5)(x)     (multiplying both sides of the equation by 5/3)\n               Rs 480000 = x    \n\nso, Bryan's property is worth Rs 480000

There are lots of them.  The easy way is to multiply 5 times 6 times 7.  This number is divisible by 5, 6, and 7.  So -- just add two to it.\n\nThis is 212.\n\nYou want another?  How about 2102?  210000000002?\n422? 420002?\n\nI got a million of 'em.
