Question 9 Comparing Quantities - Exercise

A cricket bat was purchased for ₹ 800 and was sold for ₹ 1600. Then profit earned is

(a) 100% (b) 64% (c) 50% (d) 60%

Answer:

(a) 100%

From the question, it is given that,

Cost price of the bat (CP) = ₹ 800

Selling price of the bat (SP) = ₹ 1600

Then, Profit = SP – CP

= 1600 – 800

= ₹ 800

We know that, Profit percent = (Profit/CP) × 100

= (800/800) × 100

= 100%
