sure -- check your answers -- >wink wink<
#10 is clearly
not A, since 15y does not appear in the equation
not B, since no subtraction was done (money spent)
not C, since there is no 15x
D -- we have a winner! Add 15 to x, the brother's age.
Your move.
#6,#3 look good
thank you, but i really do need help checking the answers. i cant risk getting below 70% again.

i might be wring on this one
*wrong
9. you could have immediately seen that
39:45 ≠ 6:5 , since 39<45 and 6>5
Are you just guessing
given: boys : girls = 6:5 = 6x : 5x
also given 5x = 45
then x = 9
so number of boys = 6x = 54
#8 , I think you are just guessing again.
