Solutions 1 to 5

1) Answer (d)

Let CP be Cost price and SP be the Selling Price.
From I we can get that, 5CP=4SP
We know SP for one watch. Hence CP can be calculated.
Once, CP is known profit can be calculated byProfit = SP-CP
From II we can get that, 25% of profit is gained by selling each watch.
We can Profit = SP – CP i.e 0.25CP = SP – CP
From this equation, CP can be calculated and thereby Profit.

2) Answer (b)

From problem statement we get to know that,
(x/y)=(6/5) where x and y are Anand and Sujeet’s age respectively.
Statement A introduces a new variable i.e Sandeep’s age. However, we don’t have data to form two equations to find all the three variables.
Statement B gives data in the form of known variables i.e Anand and Sujeet’s age.
Hence, we can evealute the two equations to get both the variables.
Option B is correct

3) Answer (c)

If a,b,c,d and e are salaries of A, B, C, D and E respectively the a+b+c+d+e= 65,780*5
From statement I we get, b+c = 88,545 and from statement II we get d+e=59,020
Both the statements are needed to get the salary of A.
Hence, option C is correct.

4) Answer (e)

From question statement A, we get the speed of working of women and from B we get speed of children.
However both the statement fail to give a crucial data of number of days required to complete the work for men.
This data is required if we want to calculate the speed of working of men.
Hence, data is insufficient.
Option E is correct answer.

5)Â AnswerÂ (a)

Let’sÂ assumeÂ theÂ numberÂ toÂ beÂ x.
x-(3/5)x=Â 90
(2/5)x=90
x=225

WeÂ getÂ theÂ numberÂ fromÂ statementÂ AÂ itself
HoweverÂ dataÂ inÂ statementÂ BÂ isÂ insufficientÂ forÂ findingÂ outÂ theÂ number.
HenceÂ optionÂ AÂ isÂ correct.
