a) 598268

b) 598686

c) 578486

d) 578888

1) Answer (B)

Solution:

The pattern followed here is :

Reverse(opposite) of the place values of each letter’s digits are added.

• CHANGE ⇒ XSZMTV ⇒ 24 19 26 13 20 22 ⇒ 6108424
• MODIFY ⇒ NLWRUB ⇒ 14 12 23 18 21 2 ⇒ 535932
• VISUAL ⇒ ERHFZO ⇒ 5 18 8 6 26 15 ⇒ 598686
