What should be the value of a, in the polynomials x2 - 11x + a and x2 - 14x + 2a, so that these two polynomials have common factors.A. 24B. 1C. -1D. 1/2

X^2-11x+a=0 -eq1
x^2-14x+2a=0 - eq2 subtracting both eq
- + -
--------------------
0+3x-a=0 i.e 3x-a=0 this is x=a/3
now put the value of x in eq 1
(a/3)^2-11(a/3)+a=0
a=24
putting value of x in eq 2 we will again get a=24prititripathi

Let 2 factor of eq. 1 a an bso a+b=11 n ab=asimmilarly for eq.2 ,2 factor let a n cso a+c=14 n ac=2aon solving we get 24

In the given question. n(e^t)=n(e)+n(t)-n(e or t)
n(e and t)=n - neither who speak English nor Telugu=150-30=>120.
n(e and t)=n(e)+n(t)-n(e or t)
120=55+85-n(e or t)
n(e or t)=20.
n(only Telugu)=n(t)-n(e or t)=85-20 = 65.

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!

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.
