428 : 717 :: 236 : ?

Given that 428: 717:: 236:?

From the above 428 

 $$4\times 2 = 8  (First  digit  \times  second   digit = third digit)$$

717 

$$ 7 \times 1 = 7(First  digit  \times  second  digit = third digit)$$

236 

$$ 2 \times 3 = 6(First  digit  \times  second  digit = third digit)$$

In the same way option C is follow the above pattern

(C) 339

$$ 3 \times 3 = 9 (First   digit \times  second  digit = third digit)$$

therefore Option (C) 339 Ans
