Question

1. Consider kar ek Nav hai
2. Voh ek line pe chal rahi hai
3. Line ki limit: -oo se oo tak consider karo..
4. Nav ki direction nahi pata(left or right), current position nahi pata, speed bhi nahi pata
5. Aap nav ko dekh nahi sakte, bass pata hai ki voh number line pe kahi se kahi jaa rahi hai and line nahi chodne wali
6. Nav ki speed and direction change nahi hogi

Matlab constant rahegi, chahe jo bhi ho

Now, aapko voh nav ko udana hai.. and uske liye:
A. Apke paas 1 base of operation hai
B. Apke paas infinite torpedos hai
C. Aap voh number line pe 1 minute me 1 torpedo fek sakte ho
D. Butten dabate hi 0 sec me jaha chahiye vaha torpedo foot jayega.
E. Apke paas time infinite hai(no limit)
Note: torpedo = bomb samaj sakte ho..
F. Apko ek strategy banani hai, jisse chahie voh nav jaha bhi ho, jis bhi speed se jis bhi direction me jaa rahi ho, ek na ek din apne pakad me jarur ayegi and apne torpedo se foot jaygi!!!​

Answer 1

Answer:

MATHS

The denominator of a fraction is one more than twice the numerator. If the sum of the fraction and its reciprocal is 22116, find the fraction.

Let the numerator of the fraction be x. 

Then Denominator=2x+1

Fraction =2x+1x

Reciprocal of the fraction =x2x+1

It is given that the sum fo the fraction and its reciprocal is 22116

∴2x+1x+x2x+1=22116

⇒x(2x+1)x2+(2x+1)2=2158⇒2x2+x5x2+4x+1=2158

⇒21(5x2+4x+1)=58(2x2+x)⇒105x2+84x+21=116x

⇒11x2−26x−21=0⇒11x2−33x+7x−21=0⇒11x(x−3)+7(x−3)=0

⇒(11x+7)(x−3)=0⇒x=3,−117

∵ x can not be a negative 

⇒x=3

Hence the fraction =2x+1x=73
