Hey, i correct myself.
Heres how i did it (not sure if its the correct technique)

Let x oranges are removed from the basket. The resultant should be 70 % apples

(37-x)*70/100=14
upon calculating for x, we get 17

let n oranges be removed

14/(14+23-n) = 0.7

25.9 - 0.7n = 14

0.7n = 11.9

n = 17

so D
