Question

There is a group of boys and girls waiting for school buses. 25 girls get on the bus. The ratio of boys to girls is now 3: 2. 15 boys get on the second bus. There are now the same number of boys and girls at the bus stop. How many students altogether were originally at the bus stop?

Answer 1

Any help starting this. I know the ratio is 3/5 boys and 2/5 girls at the stop. But blank where to start

Answer 2

hi @rosegreenr ..shall we start to solve this problem..?

Answer 3

yes please

Answer 4

let us start like this..
3x-15=2x
can you make out..how i got that equation

Answer 5

No. of boys and girls is same after 15 boys taking the second bus. before that there were 3X boys and 2x girls

Answer 6

@rosegreenr ..do you und stnd that ?

Answer 7

ok got it so far

Answer 8

ok ..now 3x-2x=15
x=15

so before 15 boys taking the second bus, no. of boys=3x15=45
no.of girls=2x15=30
so 45:30=3:2

Answer 9

after 15 boys taking second bus, no. of boyswill be =45-15=30
so no. of girls (30) = no. of boys (30) now
