Q:

We want to round off x, a Float to an Int value. The correct way to do so would be

A) Y = ( int ) ( x + 0.5 ) ; B) Y = int ( x + 0.5) ;
C) Y = ( int ) x + 0.5; D) Y = ( int ) ( ( int ) x + 0.5 )
 
Answer & Explanation Answer: A) Y = ( int ) ( x + 0.5 ) ;

Explanation:

Rounding off a value means replacing it by a nearest value that is approximately equal or smaller or greater to the given number.

 

y = (int)(x + 0.5); here x is any float value. To roundoff, we have to typecast the value of x by using (int)

 

Example:

 

#include

 

int main ()

 

{

 

  float x = 2.6;

 

  int y = (int)(x + 0.5);

 

  printf ("Result = %d\n", y );

 

  return 0;

 

}

 

Result : 3

Q:

A clock is started at 11 a.m. By 600 seconds past 6 p.m, the hour hand has turned through ?

A) 155 degrees B) 175 degrees
C) 205 degrees D) 215 degrees
 
Answer & Explanation Answer: D) 215 degrees

Explanation:

The total angle traced by the hour hand is the angle traced in 7 hours and 10 minutes.
We know that the angle traced by the hour hand in one hour is 30º and in one minute is 1/2º.
Therefore, (30º x 7) + (10 x 1/2º) = 215º is the angle traced by the hour hand.

Answer

From the assumption and trial and error method,


last three digits sum must leave the same digit as the answer. It is possible only if the answer must be units digit number leaving tens digit as carry.


And the possible 3rd digit is 5. Since 5 + 5 + 5 = 15 


Now, 2nd step is  1 + x + x + x = 5


=> 3x = 4


It is possible with x = 8. 8 + 8 + 8 + 1 = 25 leaving 2 as carry. 


Now, 3rd step is 2 + x + x + x = 5 => x = 1


 


Hence, the three dgits are 1, 8, 5.


185 + 185 + 185 = 555.
