- Question
Negative plus a positive equals
Options- A. negative
- B. positive
- C. zero
- D. Can't be determined
- Correct Answer
- Can't be determined
ExplanationWe know that a negative value plus a positive value always count backward and the sign depends on the bigger value sign.
When you are adding a negative number to a positive number, then the value counts backward and takes the sign of the biggest number.
For example::
Adding -5 and +2
-5 + 2 = -3 (big number is 5 and its sign is '-')
Adding -3 and +5
+5 + (-3) = 5 - 3 = +2(big number is 5 and it has sign '+').

Correct Answer: 200
Correct Answer: 24
Correct Answer: 5
Correct Answer: 190
Correct Answer: + and ?
Correct Answer: TRUE
Explanation:
We know that,
Alternate Exterior Angles Theorem::
The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent .
Converse of the Alternate Exterior Angles Theorem ::
Converse of the Alternate Exterior Angles Theorem states that, If two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel.
Correct Answer: TRUE
Explanation:
The given statement about similar triangles is TRUE.
Similar Triangles Theorem :: Similar triangles are two triangles with corresponding angles of equal measure, and the ratios of their corresponding sides' lengths are equal.
Correct Answer: O(n)
Explanation:
The worst case complexity of linear search is O(n).
Correct Answer: 20
Explanation:
6 choose 3 means number of possible unordered combinations when 3 items are selected from 6 available items i.e, nothing but 6C3.
Now 6C3 = 6 x 5 x 4/3 x 2 x 1 = 120/6 = 20.
Correct Answer: 2014
Explanation:
If After p years , commodity X will cost 60 rupees more than the commodity Y, then
320 + 60p = 740 + 20p + 60
=> p = 12
So in year (2002 + 12 = 2014), commodity X will cost Rs.60 more than the commodity Y.
