​The following pie graph shows the percentage sale of 5 brands of cars, A, B, C, D and E, during current year.

​Which of the following conclusions is NOT correct as per the data represented in the graph? ​

Correct option is A

Given:

Percentage sale of 5 brands of cars, A, B, C, D and E, during current year.

Sale of A = 37.50%, Sale of B = 25%, Sale of C = 12.50%, Sale of D = 12.50%, Sale of E = 12.50%

Solution:

Evaluate Each Conclusion:

Option A: Sale of E is double the sale of B.

Sale of E = 12.50%.

Sale  B = 25% 

​E is not double B, so this statement is NOT correct.

Option B: Sale of E is 50% of the sale of B. 

Sale of E = 12.50% and 50 % of BB B is 25 % $$\times \frac{1}{2}$$ = 12.50%

​This statement is correct.

Option C: Sales of A is greater than the sale of C and D taken together.

Sale of C + D = 12.50% + 12.50%= 25% 

Sale of A = 37.50% , which is greater than 25% 

This statement is correct.

Option D: Sale of C is less than 50% of the sale of A.

Sale of C = 12.50%, and 50% of A is 37.50 % $$\times \frac{1}{2}$$ = 18.75 %

C (12.50%) < 18.75 % , so this statement is correct.

Thus, correct answer is (a) Sale of E is double the sale of B.
