Q:

In the following set of numbers, if 1 is added to the last digit and then the orderr of digits is reversed, which number will be fourth if arranged in ascending order?

567    284    696    865    738

A) 567 B) 284
C) 865 D) 738

Answer:   A) 567

Explanation:

Here the given numbers are 

567  284  696  865  738

When 1 is added to the last digit of each of the above numbers, it becomes as follows :

568  285  697  866  739

After reversing the order of digits , we get

865  582  796  668  937

Now , when the numbers are arranged in ascending order their order becomes as follows:

582  668  796  865  937

Hence , the fourth number is 865 (a number formed by 567). Therefore option(1) is correct answer.
