The 12 balls are just distributed in the red and green balls. So there are total of $32 + 46 + 12 = \boxed{90}$

$100 - (32 + 46) = 22 - 10 = 12$

$(32 + 6) + (46 + 6) = 38 + 52 = 90$

Answer = $\fbox{90}$

If you add 32(balls out of hundred) and 46(balls out of hundred)

you get 78( Total red and yellow balls out of 100)

And subtract 78 from 100 (to get the number of yellow balls)

you get 22 minus 10(the number of balls he lost)

That's right It's 12 and divide that by 2 And you get 6

and 32(red balls) + 6 red balls is 38 and 46 + 6 = 52

and 37 + 51 = 88 + 2 balls for his birthday = 90 total Red and Green balls
