Directions: Each question is followed by two statements. You have to decide whether the information provided the statements is sufficient for answering the question.
Are the two lines, drwan in the picture parallel ?
Explanation: Statement I is redundant since the lines are drawn on the same paper, they are co-planar. Statement II tells us that the lines are parallel
Directions: In each question, you are given certain data followed by two statements. For answering the questions:
a, b,c,d and e are in A.P. Is d a positive quantity?
Explanation: The A.P. is increasing and starts with a negative number, so d can have a negative value as well as the positive value.
Directions: In each question, you are given certain data followed by two statements. For answering the questions:
How old is Sachin in 1997?
Explanation: Anil’s age was a prime number in 1996 and 1998. So Anil’s age in these two yeas can be a pair of such numbers which are prime, and differ by 2. We have many such pairs - (3,5), (5, 7), (11, 13)….. And it is not possible to arrive at a unique answer. So the answer is (1).

What is the profit percentage in the transaction?
Explanation: From statement A alone SP : CP = 2 : 5
• profit percentage = (2 – 5)/5 = 60%
• statement A alone is sufficient
From statement B alone MP = 20 & CP = 15
But as SP is not given, profit percent is cannot be determined.
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
