MATH: 1. The function f is defined for each positive three-digit integer n by f(n) = 2x3y5z , where x, y and z are the hundreds, tens, and units digits of n, respectively. If m and v are three-digit positive integers such that f(m)=9f(v), them m-v=? (A) 8 (B) 9 (C) 18 (D) 20 (E) 80 2. If x2 + y2 =1, is x + y =1? (1) xy =o (2) y = 0 3)when N is divided by 10 reminder is 1 and when N is divided by 3 remainder is 2. what is the remainder when N is divided by 30? 4) X = (1-1/2)(1-1/3)(1-1/4).....(1-1/50) what is the value of X 5) X=-1, what is the Value of X+ X^n + X^(n+1)+X^(n+2) where n is the sum of first 404 prime numbers 6) the price of a share is x$, this is increased by r% and then again increased by y$ what is the ratio of the increased price to the original price? 7) THere are 8 players and each player plays with each other player only once. every game involves only two players. waht the total number games that can be played? 8)there are 50 Black beans, 50 Red beans and 50 green beans in a jar. waht are the minimum number of beans to be picked to ensurethat atleast 14 of one color are picked? 9) there was a DS problem on the number of installments to be repaid for a loan with compound interest. 10) what is the area made by line segment y =-x+4 with the coordinate axes 11) there is a line segment L, the x-intercept of this is -ve. is y intercept of this line > x intercept. 1) (dont remember) 2) slope of the line is negative 12) a circle is divided in to 8 non overlapping arc of 10,20,30,40,50,60,70,80 degrees each 13) is XZ>YZ?? 1) XYZ=0 2) X>Y RC: 1) talked about a strategy followed by the companies to improve the employee productivity and ultimately the profits of the company. But this could improve the productivity that too only after 2yrs and then the second para an alternate approach is explained and it is concluded that the second one bears better fruits. 2) This describes a research done by some lady on the ideology of nurses profession.This was about the nurses and some ideology about their profession. Earlier no training was thought necessary cos these nurses were considered "naturals" in their profession like other females. but them later the hospital authorities in order to attain their goals they thought that a professional training for nurses was necessary. but then they interfered with training heads in deciding the content to be taught etc.. then it ends saying something like for the above reasons, this profession could not be treated to be on par with the docs etc. 3) Historians trying to establish the importance of women in old times studied some woman's suffrage movement in relation to a particular revolution in ireland(i don remember exactly..).. but this gave a distorted view because they dunno how many women actually participated and stuff like that. |
