No point is added or deducted for any unanswered question. An applicant answered 80% of the total number of questions and got a total point of 35. How many answers of the applicant were wrong? Correct Answer 4 Let the number of wrong answers be N. Number of questions answered = 80% of 50 = 80/100 of 50 = 40 Then, the number of correct answers = 40 - N Therefore,  (40 - N)×1 - N×0.25 = 35 or,  40 - N - 0.25N = 35 or,  N + 0.25N = 40 - 35 or,  1.25N = 5 or,  N = 5/1.25 = 4

In the Bengali calendar year of 1272, there was a devastating ____ in Bengal. Correct Answer Cyclone Let us solve the question by the tabular method: A is in 5th standard and likes Maths. So tick the blanks 5th standard and Maths for A and cross the rest of the Maths column. A studies with only one person who likes Bangla. I studies with two other friends who like languages.D studies in 6th standard with only one person and does not like civics. So tick the 6th standard blank corresponding to D and cross the civics blank for D. E studies with only one friend and doesn't like languages. The one who likes history doesn't study in 5th or 6th standard. D , E study with only one person. D is in 6th standard and E doesn't like languages. The remaining are B , C , G and I. I studies with two more persons who like languages. C doesn't like English and Science. So C cannot be I's classmate and can only be A's classmate because E doesn't like languages, C should like Bangla . Hence tick 5th standard and Bangla for C, cross the rest of the Bangla column. Similarly E is D's classmate because E studies with only one person and doesn't like Bangla. So tick 6th standard for E. Finally B and G are I's classmates, hence tick the 7th standard for B,G and I. Now that the standards are set, let's move to the subjects. Since B and G like only the languages and Bangla is already choosen by C, they are left with only two blanks each which are English and Science. So cross the rest of the row for B and G. The one who likes history is not in 5th and 6th. In seventh standard B and G like only languages, hence I likes history. Mark history blank of I and cross the rest of the column. Now civics column should be left with one blank , which corresponds to E. Tick the blank corresponding to civics for E and cross the rest of the row . Finally a blank in Economics column corresponding to D is left. Mark it and cross the blanks for other subjects of D's row. The table should look like below after following the above steps. Now referring to the above table we can say that (option) C & Bangla is correct answer for the above question.
