__________________
The number is 6.

Explanation:
Let the number be X, Petra added 3 then it will be X+3, multiplying the result by 4, then 4(X+3). And subtracted 6 which is 4(X+3)-6 and multiplied that result by 3 which is 3[ 4(X+3)-6] and the final answer was 90, which is 3[ 4(X+3)-6] = 90,
4(X+3)-6 = 90 Ã·3,
4(X+3)-6 = 30,
4(X+3) = 30+6,
4(X+3) = 36,
X+3 = 36 Ã· 4,
X+3 = 9,
X = 9-3
= 6.
