Correct Answer: 11 km
Explanation:
From the above result length of route -2 = 11 km
Therefore , the length of route -2 is 11 km .
Correct Answer: 8 km
Explanation:
As per the above result ,
Route -1 :- 5 + AB = 13 ? AB = 13 - 5 = 8 km
Hence , required distance between A and B is 8 km .
Correct Answer: Two
Explanation:
On the basis of above given figure , we can see that
City A is connected by 2 roads, B by 4 roads, C by 3 roads, D by 3 roads and E by 2 roads.
For a city to be starting city for such a route, it has to be connected by odd number of roads.
Hence the required answer is 2, i.e. C and D.
Correct Answer: A route can either start at C or end at C, but not both.
Explanation:
According to question ,
Here ,we will eliminate the options one by one. Option (A) cannot be true as there are many routes that satisfy the given condition. Option (C) is also not true as we can have a route starting from D (e.g. DEBDCBAC).
The route need not necessarily end at E, which is apparent. Option B satisfies all the conditions.
Hence , A route can either start at C or end at C, but not both.
Correct Answer: 560 or 510
Explanation:
If toll tax at all of the toll booths is same and let it be k then expense in each path is as follows:
Path 1: 240 + 3k
Path 2: 260 + 5k
Path 3: 260 + 6k
Path 4: 260 + 5k
Path 5: 230 + 3k
So from the given condition On solving we will get k = 50
Tool booth 3 will come in Path 3 and Path 4.
So cost incurred is:
Path 3: 260 + 6k = 260 + 300 = 560
Path 4: 260 + 5k = 260 + 250 = 510
Therefore , 560 or 510 is the cost of travel from X to Y through toll Both T3 .
Correct Answer: Wednesday
Explanation:
Clearly 1st, 8th, 15th, 22nd and 29th October are Sundays.
So, 31st October is Tuesday.
? 1st November will be Wednesday.
Correct Answer: 3
Explanation:
Three numbers in which followed by 9 and preceded 2, 3 or 4
11 [2 3 9] 4 4 5 5 5 5 [3 3 9] 8 7 7 7 8 8 8 5 5 [4 3 9] 6 6 6 6
Correct Answer: 14th
Explanation:
The change of place by Monika can be shown as under.
1 2 3 4 5 6 7 8 9 10 11 M 13 14 15 16 17 18 19 20 21
Clearly, Monika's earlier position was 8th from the left and 14th from the right end.
Correct Answer: 2
