5}none of these.

The right answer is 336.But i dont come to know how it came.

Plz help me

Answer 1

6 * (4/1) = 24

24 * (5/2) = 60

60 * (6/3) = 120

120 * (7/4) = 210

210 * (8/5) = 336

Answer 2

0 =  0 * 1

6 =  2 * 3  = 2 * (1 + 2)

24 = 4 * 6 = 4 * (1 + 2 + 3)

60 = 6 * 10 = 6 * (1 + 2 + 3 + 4)

120 = 8 * 15 = 8 * (1 + 2 + ... + 5)

210 = 10 * 21 = 10 * (1 + 2 + ... + 6)

? = 12 * (1 +2 + ... + 7)

? = 12 * 28 = 336

Choose #1.
