Arun Sharma Test: Pie Chart- 1 - CAT MCQ

5% of the time spent on each area equals 5% of the total time devoted to preparation.

Deduct first this 5% from the total time spent on solved examples, which is 10% of the total time. There is 5% of total time remaining. This remaining 5% may only pertain to a single field of study. To achieve the requisite percentage maximum, as little time as feasible must be expended on the area. Therefore, it could be either DS or LA, accounting for 10% of total preparation time.

Now, 5% = 50% of 10%, and 5% of 10% has already been allocated. 

Therefore, 50% + 5% = 55% of the time devoted on a specific area of study, say DS.

The student cannot complete the entire critical analysis at his or her friend's home. At least one subject's critical analysis must be left at a friend's house. At a friend's home, he or she covered critical analysis of no more than five subjects.

The maximum amount of time that would have been spent on tests in VA = Lower value of tests and VA = Less than 10% and 15% = 10%.

Time that would have been spent on revision in LA = the lesser of 20% and 10%, which is 10%.

He would have devoted 10% + 10% = 20% of his TIME seminars to the aforementioned topics.

Consequently, % of time devoted on the preceding two activities is = 10%+10%30%=2030=66(2/3%)

As is evident from the pie chart, brand D is the most prominent brand, followed by brand C.

26% of Brand D and 22% of Brand C were sold.

The difference amounts to 4% of the total market = 25000 × 4100=1000

• Revenue earned by brand A = ((18x25000)/100)x14500=65250000
• Revenue earned by brand B = ((14x25000)/100x13000 = 56000000
• Revenue earned by C =66,000,000.
• Revenue earned by D = ((26 x 25000)/100) x 13000 = 84500000
• Hence, D earns the maximum revenue before tax.

Revenue earned after tax = Revenue earned before tax− Tax

Therefore, brand D earned the maximum revenue after tax.

Since, when Amit sings, Bharat develops a headache and Chandu lodges a complaint. Then, we are informed that Chandu is not grumbling. Using the contra positive, the following logic results. If neither Bharat nor Chandu has a toothache or is complaining, then Amit must not be singing. Therefore, if Chandu is not complaining, Amit cannot be singing, and option (d) is the correct response.

The sentence can be rewritten as follows: "If Bhanu does not cook, Atul will consume the fruit. Whenever you encounter a "If... then" sentence in a Logical Reasoning question, the only thing that must be true is the "contrapositive"; take the opposite of each portion of the statement and reverse them. "If Atul did not eat the apple, then Bhanu did cook." Choice (b) is an ideal complement for this.
