The sum of all the digits of the positive integer q is equal to the three-digit number x13. If q=10^n-49, what is the value of n? q is of the from 99999....51 sum of digits will be 9a+5+1 =9a+6 so 9a +6 = x13 or 9a =x07 x is 2 as only 207 is divisible by 9 so 207/9 = 23 i.e 23 9's are reqd + 51 i.e ...

First Question is x+1/x-3 < 0 stmt 1: -1<x<1 so both numerator i.e x+1 & denominator i.e x -3 will be -ve for all values of x incl 0 so the expr will be -ve < 0 SUFF stmt 2: x^2 -4 <0 or x^2 <4 or -2<x<2 if x is greater than -1 say 1 then numerator would be +ve but denominator -ve so expr will b...

Hi Shiva, Congratulations for the great score :D , I do understand Quant getting over with 20 mins to spare, but how did u finish the Verbal section with 35 mins remaining :!: :!: , How did u tackle RC's & CR's so quickly, I'm really short of words to appreciate this accomplishment, hey can you ...

ans should be E

even if we combine the 2 stmts 4.8% is not above the avg i.e 67.8-56/2
so it is INSUFF

Hi Silivest, I agree with u & RI, the ans should be B stmt 1 : k= 2^10, k =2^5*7 INSUFF stmt 2 : k is not divisible by any other odd nos greater than 1 In that case it cannot have any prime factor other than 2, coz all others are odd hence k is either 2, or a power of 2, coz it cannot have any o...

If the terms of a sequence are t1,t2,t3,....,tn, what is the value of n? 1. the sum of the n terms is 3124 nos of terms may vary depending upon how the terms of the sequence relate to ecah other, eg consecutive series, AP's etc & also the starting value of the sequence INSUFF 2. the average(arit...

What is the cube root of w ? we only need value of w to solve this one (1) The 5th root of w is 64. w= 64^5 SUFF (2) The 15th root of w is 4. w= 4^15 SUFF BTW in both cases the cube root would be an ineteger only coz if we express 64 & 4 in powers of 2, then it would result in an exponent that i...
