Question

In a class, 12 students like red, 15 like blue, if the remaining 46 % like pink. Find the number of students in the class and the number of students who like pink.

Answer 1

Answer:

No.of students who like pink=23

Number of students in the class=50=27+23

Step-by-step explanation:

12+15 students make up =100%-46%

                                         =54%

27 students =54% of class population=0.54 of the class population

class  fraction =54% and 46%=0.54 and 0.46

So therefore

Using unitary method

No.of students       Class fraction

27                                  0.54

?                                      0.46

No.of students who like pink=27 x 0.46/0.54=23

No.of students who like pink=23

Number of students in the class=50=27+23
