Question

I have a bag, with some balls in it. All but four are blue, all but four are green, and all but four are red. In total, how many balls are there in the bag? The phrase “all but” can be understood like this. If I have 10 balls and I say that all but 3 are green, this means that (10−3) or 7 balls are green.

7 marbles are red !

THIS IS HOW :

total marbles =x

no. of blue marbles=x-15

no. of red marbles =x-13

no. of green marbles = x-12

so , x-15 +(x-13)+x-12 = x

3x-40 =x

x =20

RED MARBLES = x-13 = 20-13 = 7
