Step I : 710, 316, 436, 519, 868, 245, 689
Step II : 710, 316, 245, 519, 868, 436, 689
Step III : 710, 316, 245, 436, 868, 519, 689
Step IV : 710, 316, 245, 436, 519, 868, 689
Step IV is the last step of input.


If 655, 436, 764, 799, 977, 572, 333 is the input which of the following steps will be

‘333, 436, 572, 655, 977, 764, 799’ ?



A II
B III
C IV
D I
E None of these

The numbers will be arranged as sum of its digit in ascending order and in each step the numbers be interchanged.

Input: 655 = 6 + 5 + 5 = 16

436 = 4 + 3 + 6 = 13

764 = 7 + 6 + 4 = 17

799 = 7 + 9 + 9 = 25

977 = 9 + 7 + 7 = 23

572 = 5 + 7 + 2 = 14

333 = 3 + 3 + 3 = 9

Input: 655, 436, 764, 799, 977, 572, 333

Step 1: 333, 436, 764, 799, 977, 572, 655

Step 2: 333, 436, 572, 799, 977, 764, 655

Step 3: 333, 436 572, 655, 977, 764, 799

Step 4: 333, 436, 572, 655, 764, 977, 799

So, It will arranged in 4 steps.
