A sheet of paper has statements numbered from 1 to 40. For each value of n from 1 to 40,
statement n says "At least and of the statements on this sheet are true." Which statements are true and which are false?

a)The even numbered statements are true and the odd numbered are false.
b)The first 26 statements are false and the rest are true.
c)The first 13 statements are true and the rest are false.
d)The odd numbered statements are true and the even numbered are false.

please xplain properly.......

• Explaining the solution to these questions is difficult. It needs oral explanation. But I will tell the logic here not the whole process.
  If given:
  1)"At least n of the statements on this sheet are false"
  A)First half are true and last half are false.
  2)"Exactly n statements on the sheet are false"
  A)Last but one is true and rest are false
  3)"At least n of the statements on this sheet are true"
  A)In this case first x statements are true and remaining false. x can be any integer. you can get it in options. In this case it is 13. C is right.

• the answer is c
  as here at least i.e. minimum number of statements are true
  so from options we can get that first 13 statements are true and rest are false..thats it

• At least and of the statements on this sheet are true......what does this mean it should be "At least n of the statements on this sheet are true".
