1) 11 people are behind Jane. We know 5 more people are ahead then behind. so total is 17. 1 is true. so answer can be A or D. 2) total number are 3 times people behind her. let people behind her be x. Total people are 3x. We know that people ahead are 5 more than behind. so people ahead are 5+x. So...

my pick is E. S1 not sufficient. it's simple as country X percentage can be anything and we don't know where it may fall. S2 on it's own is not sufficient as 6 countries can have higher then 4.8% each. e.g. 11% each. S1& S2 combined: the two remaining of top 6 have combined percentage of 11.8%. ...

durgesh, pls tell the OA

raunekk, u don't have to pick up every number from 0 to 100. here is how i came with 47: i) All prime numbers are odd ii) all even numbers between 2 & 100 are multiples of 100 iii) Odd number multiplied by 2 gives even. so all odd number less than 50 when multiplied by 2 will be less than 100 an...

answer is D. 4 and 14 solve for smallest integer; 3*4=12. but it's smaller than 15; 4*5=20 falls within range. so smallest integer is 4. solve for largest integer 13*14=182; try 14*15= 195. so largest integer is 14. if you go for any number above 14 e.g 15 then multiple 15*16 will be out of range. s...

raunekk, here is the solution All prime numbers less than 47 are multiples of h(100). this mean h(100) is divisible by the prime number. However when you add 1 to h(100) the prime number won't be able to divide this new number. The idea is whenever a number x divides a certain number y and u add 1 t...

sorry sulabh, my bad. a blopper

umaa, u have made two mistakes. 1) ur drawing shows that u haven't taken centre as vertex for one side. The triangle line is maybe passing thru centre but not is not a vertex. A vertex at centre means that it's a meeting point for two different sides of triangle. 2) you have already assumed the area...
