The percentage increase in the number of pens sold by a trader from Tuesday to Wednesday is same as the percentage decrease in the number of pens sold from Monday to Tuesday. On Wednesday the trader sold 16 pens more than those he sold on Tuesday. If the percentage decrease in sales from Monday to Tuesday is 20%, how many pens did he sell on Tuesday ?

A. 20

B. 96

C. 100

D. 80

Answer : D. 80

Explanation:

Let number of pens sold on tuesday be x given that the percentage increase in the number of pens sold by a trader from Tuesday to Wednesday is same as the percentage decrease in the number of pens sold from Monday to Tuesday.

Percentage increase in sales of pen from tuesday to wednesday = Percentage decrease in sales from monday to tuesday = 20% then on wednesday trader sold 16 more pens than those sold on tuesday.

So number of pens sold on wednesday = x + 16 and this is 20% more than number of pens sold on tuesday
[1 + (20/100) ] * x = x + 16
6x/5 = x + 16
x = 80
So number of pens sold on tuesday x = 80.

Chauncy, an English bulldog, received 1200 votes in the Mr Bulldog USA competition, giving him approximately 30 percent of the vote. Approximately what percent of the remaining votes would he have needed to receive in order to win 70 percent of the total votes ?

A. 49

B. 55

C. 59

D. 57

Answer : D. 57

Explanation:

Let the total vote is x. then 30% of x = (30/100) * x=1200, or x = (1200 * 100) / 30 or x = 4000
Now, 30% of votes already given…so other 70% of x votes = (70/100) * 4000 = 2800 votes.
Now other needed votes = (70 – 30)% = 40% votes.
So 40% votes of x = (40/100) * 4000 = 1600;
Now he have needed only % of votes = (100 * 1600) / 2800 = 160000 / 2800 = 57.14285714%

A. 75

B. 50

C. 25

D. 33.33

Answer : C. 25

Explanation:

Let initially there were 100 labour and total work load was 100 units, so each labor’s work = 1 unit.
When there are 33.33% or (100/3) % more labour, total labours = 100 + (100/3) = 400/3
As 400/3 labours has to complete the same work of 100 units, so each labour’s work = 100 / (400/3) = 3/4 unit.
Hence % reduction in the work load of each labour = (1- 3/4) * 100/1 = 100/4 = 25.
