Correct Answer:
Explanation:
Correct Answer: II and III only
Explanation:
From above given statement , we can see that
I. Perimeter of the rectangular hall = 2 ( length + breadth ) = 76 m
? 2 ( L + B ) = 76
? L+ B = 38
II. Area of the hall = 336 m2
? length x breadth = 336 m2
III. Cost of flooring per square metre = $550.
Combining (II) and (III),
Total cost = Area of the hall x Cost of flooring per square metre
= 336 × 550 = $184800.
Correct Answer:
Explanation:
None of the statements give the amount of labelled price or SP. So, even by combining all the statements together, question cannot be answered.
Hence ,we cannot find the amount of profit earned because all the above given information are not sufficient .
Correct Answer:
Explanation:
As per given above statements , we have
Let, the price of 1 dozen oranges, 1 dozen banana and 1 dozen apples be x, y and z, respectively.
I. Price of 2 dozen oranges and 1 dozen banana = $110
? 2x + y = 110
II. Price of 3 dozen apples and 1 dozen banana = $170
? 3z + y = 170
III. Price of 1 dozen oranges and 1 dozen apples = $95
? x + z = 95
we find the price of 1 dozen oranges .So, by combining all, we get the values of x = 45.
Correct Answer: If the data in either Statement I alone or in Statement II alone are sufficient to answer the question
Explanation:
From Statement I,
Total weight of Arun, Suraj and Vinay = 3 x Average weight = 3 x 68 kg
? Arun's weight = 3 x 68 - (78 + 46) = 80 kg
Now, total weight of Raju and Pradeep = 2 x 72 = 144 kg
? Pratap's weight = 144 - 68 = 76 kg
? Second highest weight = 78 kg
(Suraj's weight)
From statement II,
Total weight of Arun, Suraj, Vinay and Raju = 4 x 68 = 272 kg
? Arun's weight = 272 - (78 + 68 + 46)
? Arun's weight = 272 - 192 = 80 kg
? Second highest weight = 78 kg (Suraj's weight)
