The cost price of a chair is 21,800. Later, its cost price becomes 22,100. What is the percentage increase in the cost price of the chair?
Answer & explanation
Correct answer: option 2
First cost price = 21,800
Second cost price after increment = 22,100
Increment = 22,100 - 21800 = 300
Increase% = 300 × \(\frac{100}{21800 }\) = 1.37%
