In July 2018, if the sales of cars by the dealer D increases by the same percentage as in June 2018 over its previous month, then what is the number of cars sold by D in July 2018?
Answer & explanation
Correct answer: option 3
Percentage increase in sale of D in June = \(\frac{180}{600}\) × 100
= 30%
( percentage of sale is same for June and July )
Total sale of D in July = 780 + \(\frac{3}{10}\) × 780 = 1014
