Question

As part of the 'Learning Journey' program, 73 pupils travelled on two buses, one air-conditioned and one non-air-conditioned, to the Singapore Discovery Centre. Three-fifths of the pupils on the air-conditioned has wee girls. There were 17 boys in the non-at, conditioned bus. The number of girls on the two buses were equal. How many pupils wee there on the air-conditioned bus?

Answer 1

g/2 on each bus
b-17 on ac bus, 17 boys on hot bus

g + b = 73 so b = 73-g

on ac bus:
3/5[ g/2 + (b-17)] = g/2

6 [g/2 + (56-g)] = 5g

3 g - 6 g + 336 = 5 g

8 g = 336

g = 42 girls total
b = 73 - g = 31 boys total
so on ac bus
g/2 = 21
b-17 = 14
35 total on ac bus

Answer 2

How did u get 42 ??? I still dont understand
