(1)X^3=+ve 2digit odd --> X =+ve odd { odd x odd x odd= odd}

---> 1, 3, 5, 7,9....

1^3=1, 3^3=27; 5^3=125.....hence X=3

(2) X^4=+ve 2 digit odd --> X =+odd or -ve odd

----> ..-5, -3,-1 or 1, 3, 5, 7,9....

1^4=1, 3^4=91; 5^4=625.....hence X= +3

(-1)^4=1; (-3)^4=91; (-5)^4=625..... hence X=-3

Ans is A
