maths questions can be solved using unitary method.
Answer:
(a) The total number of girls in the class are 48
(b) The total number of students that like maths are 80
(c) The total number of boys like maths are 45
Solution:
According to the question, [tex]\frac{3}{5}[/tex] of total students are boys
number of boys = [tex]\frac{3}{5}[/tex] × 120 = 72
Also, According to the question, [tex]\frac{2}{3}[/tex] of total students like maths
number of students = [tex]\frac{2}{3}[/tex] × 120 =80
(a) The total number of girls in the class = total number of students - total number of boys
total number of girls in the class = 120 - 72 = 48
(b) The total number of students that like maths are 80
(c) The total number of boys like maths = total number of students that like maths - total number of girls that like maths
total number of boys like maths = 80 - 35 = 45
