is question me first and third number ko interchange krna tha.

Question:
DIRECTIONS- These questions are based on the following set of numbers :


642 756 835 478 564

If in each number, 1 is added to the first digit and the position of the second and the third digits are interchanged, which number will be the largest ?
Options:
A) 642
B) 756
C) 835
D) 478
E) 564
Solution:
642 \(\Rightarrow\)742, 756 \(\Rightarrow\)856, 835 \(\Rightarrow\)935, 478 \(\Rightarrow\)587, 564 \(\Rightarrow\)664


After interchanged the positions of the second and third digits, numbers will be

742 \(\Rightarrow\)724, 856 \(\Rightarrow\)865, 935 \(\Rightarrow\)953, 578 \(\Rightarrow\)587, 664 \(\Rightarrow\)646


Hence, largest number will be 953 or 835
