ans:C
The rule to take the least number is not correct.
THE ACTUAL METHOD IS LETS say that option A is correct.
then 20th statement becomes true. and it says atleast 20 statements are true. but there are no 20 true statements if option a is correct. Hence this statement is false.
lets say B is correct then according to this 14th statement is true but there are no 14 true statements in total so option B is also not correct.
Consider C is true statement then going according to C, we see that 6 th statement says "atleast 6 statements are true".This condition is satisfied as we are considering first 6 statements are true. Same with remaining conditions.Hence option C is the correct answer.
If the option is all the first 7 statements are true. Then it also can satisfy the conditions.So in the question atleast n statements are true. the option which states "the first x statements are true and the rest false is the correct answer.
