The graph given below represents the number of students (in thousands), who opted for the given three subjects during the given four years.

Out of the total number of students who opted for the given three subjects in the year 2022, 42% were girls. How many boys chose the given three subjects?

The correct answer is

40,600

Total number of students in 2022 = 40,600

Percentage of girls = 42%

Number of girls = (42/100) × 40,600 = 17,052

Number of boys = 40,600 - 17,052 = 23,548

Hence, the number of boys is 23,548.
