Data Interpretation and Caslets Solutions

Answer 1: d
From the table we clearly seen that highest % increase is for D in Feb. i. e 25%

Data Analysis and Interpretation Caselets

Answer 2: a
The greatest absolute change in the market value is 20 i.e. In
the month of March the share of A = 115 – 95 = 20

Answer 3: a
The greatest percentage change in any share was recorded for share D f or the month of February viz. 25%

Answer 4: d

Data Analysis and Interpretation Caselets

Due to share value changes the maximum loss is 10 for the month of Jun e. Hence the answer is (d).

Answer 5: a
From the above table again w e can see that the individual’s highest gain is Rs.5.

 Answer 6: a
Total number of batches = 1000
Let p be the total number of bad widgets
Therefore the total number of good ones will be (1000 –p).
On test I his total cost will be = Rs.2 (1000) + 25 x 0.8p + 50 x 0.2p
On test 2 his total cost will be = Rs. 3(1000) + 25 x p
Now, it will be worth testing if the cost of testing is less than the cost of penalty levied on the defective pieces. Let us check all the choices:

Data Interpretation Questions Solutions

Above 100 defectives cost is cheaper than the penalty.
But for 100 defectives the cost of penalty is the same as that for testing.
Therefore we come to this conclusion that below 100 defectives, the penalty will be less than the cost of testing and hence it is not worth testing.

Answer 7: d
If there are 120 widgets, he should go for test I as it is cheaper.

Answer 8: c
From the table, we can say that if the number of defectives is between 200 & 400, he should go for Test II as it is cheaper.

Answer 9: a
In case of 160 defectives, he should use test I as it is cheaper.

Answer 10: a
As the cost of both the Tests is same = Rs.8000.
Prakash may use either Test I or Test II for 200 widgets
