Select the option that is related to the third number in the same way as the second number is related to the first number.

428 : 717 :: 236 : ?

339

The pattern followed is,

1st digit  of term × 2nd digit of term = 3rd digit  : 1st digit  of term × 2nd digit of term = 3rd digit

428 : 717

4 × 2 = 8

7 × 1 = 7

So,

428 : 717

Similarly,

By observing all options we find that only option 1 follow the same patter .

236 : ?

2 × 3 = 6

And,

3 × 3 = 9

So,

236 : 339

339 , is correct answer .
