CORRECT QUESTION: Sum of the consequent 7 integers equals
1617. Find the no. of prime numbers in that sequence.
SOLUTION:
Let the numbers be x, x+1, x+2, x+3, x+4, x+5, x+6
Since their sum equals 1617, we have-
x+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)+(x+6)=1617
7x+21=1617
7x=1596
x=228
Hence the numbers are: 228,229,230,231,234,235,236
Prime Numbers: 229, 231.
SOLUTION:
Let the numbers be x, x+1, x+2, x+3, x+4, x+5, x+6
Since their sum equals 1617, we have-
x+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)+(x+6)=1617
7x+21=1617
7x=1596
x=228
Hence the numbers are: 228,229,230,231,234,235,236
Prime Numbers: 229, 231.
total no. of

let A=soccer players..B=basket ball players..C=vollyball
players
n(A U B U C)=n(A) + n(B) + n(C) - n(A INTERSECTION B) - n(A INTERSECTION C) - n(C INTERSECTION B) + n(A INTERSECTION B - INTERSECTION C)
therefore..
100=50+45+50-intersections+15
hence..intersections=145-100+15=60play only 2 games..
n(A U B U C)=n(A) + n(B) + n(C) - n(A INTERSECTION B) - n(A INTERSECTION C) - n(C INTERSECTION B) + n(A INTERSECTION B - INTERSECTION C)
therefore..
100=50+45+50-intersections+15
hence..intersections=145-100+15=60play only 2 games..
An exam consists of
200 questions to be solved in 3 hours, out of which 50 are maths questions. It
is suggested that twice as much time be spent on each math question as for each
other question. How many minutes should be spent on maths problems?
x=time for each math problem
y= time for every other problem
50x+150y=180 minutes
x=2y because spent twic as much time on the math problems as the other
50(2y)+150y=180
100y+150y=180
250y=180
y= 180/250=18/25 of a minute per problem on the other questions
x=2(18/25)
x=36/25 minutes

How To Write A C-Program Without Using main()
Function?
#include<stdio.h>
#include<conio.h>
#define Encyp(m,a,h,e,s,g,t) m##h##s##e
#define begin Encyp(m,e,a,n,i,n,g)
int begin()
{ clrscr();
printf(” hello “);
getch();
Explaination:
Does the above program run without main function?
Yes, above program runs perfectly fine even without a main function. But
how, whats the logic behind it? How can we have a C program working without
main?
Here we are using preprocessor directive #define with
arguments to give an impression that program runs without main. But in
reality it runs with a hidden main function.
The ‘##‘ operator is called token pasting or token
merging operator. That is we can merge two or more characters with it.
NOTE: A
Preprocessor is program which processes source code before compilation.
Look at second line of program -
#define Encyp(m,a,h,e,s,g,t) m##h##s##e
What is the preprocessor doing here. The macro
Encyp(m,a,h,e,s,g,t) is being expanded as “mhse” ( ## operator merges m,h,s
& e into mhse). Logic is when you pass (m,a,h,e,s,g,t) as argument it
merges the 1st,3rd , 5th & 4th characters(tokens).
Now look at third line of program -
#define begin Encyp(m,e,a,n,i,n,g)
Here preprocessor replaces macro “begin”
with expansion Encyp(m,e,a,n,i,n,g). According to macro definition
in the previous line argument must be expanded so that 1st, 3rd,
5th & the 4th characters must be merged. In the argument (m,e,a,n,i,n,g)
1st,3rd,5th & 4th characters are ‘m’,’a’,’i’ & ‘n’.
The number of arguments passed in pre-defined
statement Encyp and begin Encyp must be the same. Length of “m,a,h,e,s,g,t” is
equal to length “m,e,a,n,i,n,g”. If length do not match compiler
will throw an Error saying wrong number of arguments in call of macro ‘Encyp’
and declaration terminated incorrectly.So third line “int begin” is
replaced by “int main” by preprocessor before the program is passed on for
the compiler. That’s it…
Final Thoughts
The bottom line is there can never exist a C program without
a main function. Here we are just playing a gimmick that makes us beleive
program runs without main function, but actually there exists a hidden main function
in the program. Here we are using proprocessor directive to intelligently
replace the word begin” by “main”. In simple words int begin=int main.
