Accenture Sample Logical Equation Questions

Question 1
If 11 + 21 = 3, 34 + 45 = 32 and 42 + 53 = 23 then 64 + 75 = ?
a)59 b)43 c)69 d)53
Answer : a)59
Solution :
Let AB be the first number of the addition and CD be the second one. By closely observing, we can conclude that questions are in the general form AB + CD = (A x B) + (C x D).
i.e.,11 + 21 = 1 x 1 + 2 x 1 = 1 + 2 = 3
34 + 45 = 3 x 4 + 4 x 5 = 12 + 20 = 32
42 + 53 = 4 x 2 + 5 x 3 = 8 + 15 = 23.
Therefore, the result for 64 + 75 = 6 x 4 + 7 x 5 =24 + 35 = 59.
Question 2
If 15 + 22 = 32, 19 + 35 = 62 and 23 + 49 = 101 then 34 + 52 = ?
a)91 b)101 c)172 d)72
Answer : c)172
Solution:
By observing the question we can generalize the equations to, AB + CD = (AB x C) + D
Then,
15 + 22 = (15 x 2)+ 2 = 30 + 2 = 32
19 + 35 = (19 x 3)+ 5 = 57 + 5 = 62
23 + 49 = (23 x 4)+ 9 = 92 + 9 = 101
Similarly,34 + 52 = (34 x 5)+ 2 = 170 + 2 = 172
Hence 172 is the required answer.
Question 3
If 3 + 5 = 19, 5 + 9 = 61 and 9 + 12 = 117 then 13 + 14 = ?
a)128 b)152 c)124 d)183
Answer : d)183
Solution:
The above question seems to be in the general form A + B = (A x B)+(A - B)2
3 + 5 = (3 x 5)+(3 - 5)2 = 15 + 4 = 19
5 + 9 = (5 x 9)+(5 - 9)2 = 45 + 16 = 61
9 + 12 = (9 x 12)+(9 - 12)2 = 108 + 9 = 117
Similarly, 13 + 14 = (13 x 14)+(13 - 14)2 = 182 + 1 = 183.
Hence the answer is 183.

Two sticks and matchbox, measure exactly 45 minutes by burning these sticks

Question: You have two sticks and matchbox. Each stick takes exactly an hour to burn from one end to the other. The sticks are not identical and do not burn at a constant rate. As a result, two equal lengths of the stick would not necessarily burn in the same amount of time.  How would you measure exactly 45 minutes by burning these sticks? Answer: This puzzle used to be asked in Wall Street interviews long time ago. It is very rare for this question to be asked now but it is a very good question to help you think a little outside the normal thought process. The answer is really simple. Since the sticks do not burn at a constant rate, we can not use the length of the stick as any sort of measurement of time. If we light a stick, it takes 60 minutes to burn completely. What if we light the stick from both sides? It will take exactly half the original time, i.e. 30 minutes to burn completely. 0 minutes – Light stick 1 on both sides and stick 2 on one s...
