A six-day – Monday through Saturday – campus placement drive was conducted in ABC institute of Technology to provide jobs to the engineering students from the different branches - Electrical, IT, Mechanical, Civil, and Chemical. On each of the six days, no two branches had the same number of students being placed. Moreover, the number of students placed in each of the branches was more than one but less than eleven.The table below gives partial information of the number of students who got placed from Monday through FridayThe other known facts about the number of students getting placed is as follows:(i) The number of students placed from Electrical branch on Monday and that from IT on Saturday were 5 and 2 respectively.(ii) On any day, if the number of students who got placed from Electrical branch was more than that from Chemical branch, then the number of students who got placed from IT branch must be less than that from Civil branch. Conversely, if the number of students who got placed from Electrical branch was less than that from Chemical branch, then the number of students who placed from IT branch must be more than that from Civil branch.(iii) The number of students who got placed from Mechanical branch were equal on exactly two days - Monday and Saturday.(iv) The sum of number of students who got placed from Chemical branch on Wednesday and Thursday was equal to the number placed on Monday.(v) The number of students who got placed from Civil branch on Saturday is equal to the number of Electrical branch students who got placed on Tuesday.(vi) On each of these days for exactly these two branches (as shown in the table above) the number of students who got placed on that day was equal to those getting placed on the next day (Tuesday through Saturday) . However the two branches cannot have exactly the same numbers placed the next day.For example: Based on the table above, we can determine that on Tuesday, the number of students placed from any two branches will be 9 and 6, but those cannot be IT and Civil, respectively. Similarly, on Wednesday, the number of students placed from any two branches will be 2 and 7, but those cannot be Mechanical and Chemical, respectively.Question No 30.How many IT engineering students got placed on Wednesday?
