Solution: 
Any tangent to the parabola ?? 2
= 4?? is ?? = ???? +
?? ?? 
Comparing it with ?? = ???? + 4, we get 
1
?? = 4 ? ?? =
1
4
 
Equation of tangent becomes ?? =
?? 4
+ 4  
?? =
?? 4
+ 4 is a tangent to ?? 2
= 2????  
? ?? 2
= 2?? (
?? 4
+ 4)  
Or 2?? 2
- ???? - 16?? = 0, 
?? = 0  
?? 2
+ 128?? = 0, 
? ?? = 0 (not possible), 
     ?? = -128 
5. If ?? and ?? are two real roots of the equation ( ?? + 1)tan
2
?? - v 2 ?? tan?? = 1 - ?? , where ( ?? ? 1) 
and ?? are real numbers. If tan
2
( ?? + ?? ) = 50, then value of ?? is              
a. 10 b. 5
c. 7 d. 12 
Answer: ( a) 
Solution: 
( ?? + 1)tan

?? - v 2?? tan?? = 1 - ?? 
tan

( ?? + ?? )= 50 
Now,  
tan?? + tan?? =

Answer: ( b) 
Solution: 
Let the equation of ellipse be 
?? 2
?? 2
+ 
?? 2
?? 2
= 1 ( ?? > ?? ) 
Now   2???? = 6  &  
2?? ?? = 12 
? ???? = 3  &   
?? ?? = 6 
? ?? 2
= 18    
? ?? 2
?? 2

7. The logical statement ( ?? ? ?? )? ( ?? ?~ ?? ) is equivalent to 
a. ~ ?? b. ?? c.  ?? ? ?? d. ?? ? ??  
Answer: ( a) 
Solution: 
 
?? ?? ?? ? ?? ~ ?? ?? ?~ ?? ( ?? ? ?? )? ( ?? ?~ ?? ) 
       T        T                  T         F             F                       F 
       T        F              F         F             T                       F

Solution: 
Let 5 numbers be ?? - 2?? , ?? - ?? , ?? , ?? + ?? , ?? + 2??  
5?? = 25  
?? = 5  
( ?? - 2?? ) ( ?? - ?? ) ?? ( ?? + ?? ) ( ?? + 2?? ) = 2520
