Correct answer: B
Explanation
Leads generated by e-marketing in 2003 = (100% - 25%) x 100,000
= 75,000
Therefore leads generated by newspaper advertising in 2003
= (17.5%/25%) x 75,000 = 52,500
Alternatively
25% of x = 75,000
X = (75,000 x 100)/25
= 300,000
Since newspaper advertising for 2013 = 17.5%
=> 17.5/100 x 300,000 = 52,50
