Imp Pts regarding Floor based puzzles:- 1. A lives immediately above the floor of B means A is just above B 2. A lives immediately below the floor of B means A is just below B 3. A lives above the floor of B does not mean that A is just above B but A can be placed on any floors above B n same as vice versa . 4. A lives two floors above B means If B is placed on the first floor then A is placed on the third floor n same as vice versa .

Questn asked in the niacl assistant exam 2017 - Simple Interest obtained on an amt. of 'P' at the rate of 8% per annum for 5 years is equal to the simple interest obtained on an amt. of 'P+500' at the rate of 9% per annum for 4 years.Find the principal. Sol- > 40%P=36%(P+500) we get P=4500 ans
Bhaiyo..aisi puzzles ko solve krne me kitna tym lagta hai aap logo exactly- Eight representatives A, B, C, D, E, F, G and H participated in a conference in which they were sitting around a circular table facing the centre. All the eight representatives are from four countries named- India, Australia, Pakistan and China, i.e. exactly two are from each country, but not necessarily in the same order. These representatives are from different companies- HP, Microsoft, Apple, IBM, Infosys, TCS, Honda and Hyundai. The representatives of Infosys and Apple do not sit opposite to each other. No two representatives of the same country are sitting adjacent to each other except those from Pakistan. D is neither representing Hyundai nor Apple. The representative from Honda is sitting to the immediate right of the representative from Hyundai. C, who is representing IBM, is from India. The representative of HP is not from China. C sits to the immediate right of F, who is from Pakistan. F is not representing Apple. B is not a representative from China. B is sitting opposite E. Representatives from China are sitting opposite each other. A sits to the immediate left of the representative of Infosys. The representative of Infosys and the representative of Honda are the immediate neighbors of the representative of TCS. B does not represent HP. The representatives of Microsoft and Hyundai are not sitting adjacent to each other. B does not sit adjacent to the representative from India. G and H neither sit opposite to each other nor adjacent to each other. Both the representatives from Australia are sitting adjacent to representatives from China.
is digital root technique applicable to all simplifications ?

Digital Root is the single number obtained by adding the number successively. E.g. Digital Root of 347 = 3 + 4 + 7 = 14, 14 = 1 + 4 = 5. Thus, 5 is the a single digit number, which is the digital root/ seed number of 347. Properties of Digital Root 1. When you multiply any number by 9, the digital root will always be 9 eg. 7 X 9 = 63. 6 + 3 = 9
2. When we add 9 to a number, it does not change the digital root of that number e.g. 417 = 4+1+7= 12, 1+2 = 3
Now, if we annex 9 to this number i.e. 4179 = 4+1+7+9 = 21, 2+1 = 3 . 3. When we divide any number by 9, the digital root of that number will be the remainder e.g. 13/9 remainder is 4 which is same as digital root of 13 (1 + 3 = 4) 47/9 remainder is 2 which is again same as 4 + 7 = 11, 1 + 1 = 2. 4. Digital root of any number will be from 1 to 9 5. Digital root of any perfect square will fall among 1, 4, 7, 9 only
e.g. 16 = 1 + 6 = 7
36 = 3 + 6 = 9
49 = 4 + 9 = 13, 1 + 3 = 4
64 = 6 + 4 = 10, 1 + 0 = 1
Guess the wrong ans.... I think it's option A.
