A total of 3000 chocolates were distributed among 120 boys and girls such that each boy received 2 chocolates and each girl received 3 chocolates. Find the respective number of boys and girls?

40, 80

50, 70

60, 60

70, 50

Let the number of boys be x.

Number of girls is 120 – x.

Total number of chocolates received by boys and girls = 2x + 3(120 – x) = 300

=> 360 – x = 300 => x = 60.

So, the number of boys or girls is 60
