A man's initial salary is N540.00 a month and increases after each period of six months by N36.00. Find his salary in the eight month of the third year.
N828.00
N756.00
N720.00
N684.00
Vysvětlení
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
