Explanation Given Information: A 100 -watt light bulb is brighter than a 60 -watt bulb. Formula used: Step1: Recognize the original amount and the new amount and find the difference between them. Step2: Put the difference obtained in step 1 for the portion and the given original amount for the base in the rate formula, “ R = P B ”. Step3: Solve the equation for rate and convert the answer obtained into percent. Calculation: A 100 -watt light bulb is brighter than a 60 -watt bulb. Here, Original amount is 60 -watt . New amount is 100 -watt . Difference between the original and the new amount is, 100 -watt − 60 -watt = 40 -watt Now, value of base is B = 60 -watt as base is the original amount and value of portion is P = 40 -watt as portion is the difference between the original and the new amount
