Math Data Sufficiency-Set-2-ANSWER

1.B)

From I, we dot calculate the exact amount. There is no cost price . Hence I, is not sufficient

From II,Profit is 50 (SP-CP=50) .Hence II alone is sufficient to answer the question.

2.D) Both are not sufficient to answer the questions

3.A)

From I, The two digit number can be formed by using the digits 0,1,2,3,4,5,6,7,8,9. The difference between 0 & 9 is 9

So, the digit used is 90. Hence I is sufficient.

From II, Sum of the digits = difference of the digit. The number can be 20,30,40 etc.

Hence II is not sufficient.

4.C)

From I, we will get the diameter, which is equal to the diagonal, and area can be found.

From II “R” will be get . Hence area will get.

5.E)

From I is clear that only 80 % can speak Hindi

From I & II  20 % = 44   so 80 % = (44*80)/20= 176

6.C)

From I

480 *100= CP (100+20)

CP=450

Profit 50

From II

SP= CP + Profit

So, we get the answer

So, either I or II is sufficient to answer the question

7.B)

From I, List price is not occur, so we can’t find the answer

From II,Profit 5 %

Hence statement II is sufficient to answer the question.

8.E)

From I & II together

Let the labeled price be Rs 100

Now SP, of the suitcase =125 % of Rs 100=Rs 125

Labelled price = (2000*100)/125=1600

CP of the suitcase =1600 *3/4=Rs 1200

9.A)

From I

Cost price =120000/6=20000

Profit = 20010-20000=10

From II

Profit 20010-(20010 *100/125) =4002

From III

Profit = (20010*2.5)/100= 4002

Hence any of the three is sufficient

10.E)

Profit is not occur
