Answer is 0.5% bcoz...take n=100?then?memory m=sqrt(100n)=sqrt(10000)=100Increase n by 1% thenn=101?then memory m=sqrt(100n)=sqrt(10100)=100.5then memory will be increased by 0.5%

Suppose Qurban is x yrs.? then Jaila is 2x yrs (twice older than Qurban)If Jaila is 4 yrs younger, Qurban is 3 yrs older then their ages diff is 12 yrsso (2x-4)- (x+3) = 12Now we solve it we got x value as 19yrsSo sum of their ages is 38+19 = 57.

There are two numbers in the ratio 8:9. if the smaller of the two numbers is increased by 12 and the larger number is reduced by 19 thee the ratio of the two numbers is 5:9.Find the larger number?
karthisiva
- Dec 21st, 2010
(8/9)x*12/19=5/9,sollution multiply 8 with 9 and 9 with 5,so we get 72-45, and same for 12 and 19,we get 27x=108-95,x=13/27,x=1/2.1,largest number =9*1/2.1therfore the largest number is 4.5.
ksrikant
- Dec 19th, 2010
X:y=8:9 this means x is smaller than y(as x = (8/9)y). According to condition x+12/y-19 =5:99x+108 = 5y-95but 9x=8yso, 8y+108 = 5y-953y = -203y= -203/3, which is the larger number.

NEVER!If you are deciding the numbers of arguments on the basis of size of int in 32 bit compiler, it should be 2^31-1. that is almost square of 32767.And The memory allocated to argv is from RAM. SO do you really think compiler allocates memory holding 2^31-1 strings of any size!
