A
N828.00
B
N756.00
C
N720.00
D
N684.00
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Since the salary increases by #36 after every 6 months
: 2 years and 8 months imply an increase of five times only:
36 * 5 → #180
His salary then = initial salary + increment
= 540 + 180
= #720
Answer is C
