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.

A mother her little daughter and her just born infant boy together stood on a weighing machine which shows 74kgs. How much does the daughter weight if the mother weights 46kg more than the combined weight of daughter and the infant and the infant weighs 60% less than the daughter ?

A. 9

B. 11

C. 10

D. Cannot be determined

Answer : C. 10

Explanation:

Daughter weight is x, infant weight is 60% less than daughter (i.e. 0.4x).
Mother weight is (x + 0.4x + 46).
Total weight = x + 0.4x + (x + 0.4x + 46) = 74.
Solving the eq. x = 10
