Question

in an engineering college 40% of students belongs to cse branch,60% of the remainince branchg belongs to ece branch and remainig 240 students belongs to mechanical branch.how many students belongs to ece?

Answer 1

Answer:

Number of students belonging to ece is 360.

Step-by-step explanation:

Students belonging to cse branch= 40%

Students belonging to ece branch= 60% of the remaining( means 60℅ of 60) = 36℅

Therefore, remaining percentage of students= 100-(40+36) = 24℅

The remaining students is given as = 240( mechanical branch)

Therefore, we can say that 24℅ is equivalent to 240

So, 100℅ is equivalent to ( 240/24)*100 = 1000.

Therefore, number of students belonging to ece= 36℅ of 1000 = 360.
