A worker's salary becomes Tk. $4500$ after $4$ years and Tk. $5000$ after $8$ years. The annual increment is —

aTk. $100$
bTk. $125$
cTk. $150$
dTk.

The annual increment equals the salary rise divided by the number of years: $\dfrac{5000 - 4500}{8 - 4} = \dfrac{500}{4} = 125$ Tk. So salary increases by Tk. each year.
