Quantitative Aptitude ( CCS) Profit and loss

Selling price of a cellphone is increased by 20%. For this sale is decreased by 30%. Find the effect of total sales?

12%

16%

20%

24%

Let cost of each cell phone = Rs.100 & Sale = 100 phones.

Money receipt = Rs.(100 x 100) = Rs.10,000

New cost per cellphone = Rs.120 and New sale = 70 phones

New Money Receipt = Rs.(70 x 120) = Rs.8400

Then the effect of sales = decrease in money receipt = 1600 /10000 = 16%

Hence, option 2 is the correct answer.
