Directions: In each question, you are given certain data followed by two statements. For answering the questions:
Is xy + yz + zx positive?
Explanation: The answer could not be achieved even by both the options together.
Directions: In each question, you are given certain data followed by two statements. For answering the questions:
What is the ratio of the two liquids A and B in the mixture finally, if these two liquids kept in three vessels are mixed together? (The containers are of equal volume)
Explanation: There is a catch in the problem. Although the containers are of equal volume, it is not known to what extent these containers are filled by the liquids A and B. (i.e. the first container might be half full, while the second might be two-thirds full). Until such details are known, the final ratio of liquids A and B cannot be found out. Thus, the answer is (1).
Directions: Each question is followed by two statements. You have to decide whether the information provided the statements is sufficient for answering the question.
What is the volume of the cylinder?
Explanation: From statement A, no information is given about the other two sides.
From statement A, as the height of the cylinder is not given, its volume cannot be determined.
From statement B, as the volume of the cone with the maximum possible volume that exactly fits into the cylinder is 100 cubic cms which implies the volume of the cylinder is 3 x 100 = 300 cubic cms.
Directions: In this Question , Each Alphabet used is for a distinct digit & the equation given is mathematically true .
Explanation:
OAT+OAT+OAT = BOOT. As T=0, no carry for A+A+A(3A). Possible values of A and O can be calculated by
1) 3A= O
2) 3A = 10 +O
3) 3A = 20 + O
Here Largest carry generated by addition of three one digit number is 27(9+9+9).
Hence value of O is less than 7 for equation 3.
For Equation 3)
Assume value of O is 7. Therefore value of A=9
now carry + O + O + O = BO.
(2) + (7) + (7) + (7) = 23.
but 7 is not equal to 3. Contradict to our assumption.
Try another value of O as 4 for equation 3
O=4 therefore, A = 8.
now carry + O + O + O = BO.
(2) + (4) + (4) + (4) = 14.
hence value satisfied with our prediction. hence O=4 A=8 and B=1
now TOO + TOO = TAA
044 + 044 = 088
