Below we have given a few questions and answers on Multiple Choice. These questions will help you solve questions on multiple choices

Question 161

If r/m = 0.595, then m/r is equal to which of the following?

1. 0.674
2. 2.67
3. 776
4. 78
5. 14

Explanation: Make the base on both sides of the equation the same. 32768 is similar as 85. So 85x = 85, which means that r = 1.

Question 162

If u – 8 = 8 (1 – u), then what is the value of u?

1. 1.6
2. 0.75
3. 5.86
4. 85
5. 9

Explanation: The fraction p/m is a equal to v/y. To find the numerical value of v/y just turn the numerical value of v/y; this comes to 0.724. Your calculation will tell you that 1/0.724 = 1.6.

Question 163

The distance between the points (-7, 3) and (-7, -18) is

1. 0.76
2. 67
3. 12
4. 25
5. 0.89

Explanation: Notice that a coordinate in both points is the same. So you just have to find the difference in the b coordinates. The difference is 7 – (-18) = 25

Question 164

If k(m) = 2m2 + 2 then what is the value of k, where m = 2?

1. 5
2.    45
3. 0.56
4.    46
5.    5

Explanation: Put the value of m in the equation
K(2) = 2 * 22 + 2
2k = 10
K = 5

Question 165

If z = log, (zx) then mz =

1. 6z
2.    mx
3. 78
4.    1.8m
5.    78

Explanation: If (mx) = z is a component then d that turn z into yz. You can compute the value of z = 3.0103. The only answer choice that equals to 1,024. Therefore (b) is the answer.

Question 166

If 9r + 2v = 11 and z – 3v = 5, then what is the value of k?

1. 0.7
2. 8k
3. 0.68
4. 8
5. 2.0

Explanation: When you have two equations which is very similar in form you are probably looking at classic ETS style simultaneous equations. Adding the two equations cancels out the v term leaving you with the equation 8r = 16, so k = 2

Question 167

If k – r > k + r, then which of the following must be true?

1. 5
2. r < 8
3. k > 6
4. r > 9
5. 8k

Explanation: Algebraic manipulation is the easiest way to solve this problem. You need to add r to each side which will give inequality k > k + 2r. Now you are required to subtract from each side to get 0 > 2r and you will find your answer is (b)

Question 168

h varies directly as the square of p. When h = 2.5, p = 0.5 If h = 80, then p would be equal to

1. – 2 √2
2. 89
3. 75
4. 90
5. 85

Explanation: If h varies directly as the square of the x, it means h / p2 will always have the same value. So set up a proportion 2.5/(0.5)2 = 80/p2. You require to cross multiply and solve p2 = 8. Therefore p = +2√2

Question 169

If b – z > b + z, then which of the following must be true?

1. 6b
2. z < 8
3. h78
4. 4
5. 6/9

Explanation: Algebraic manipulation is the best way to solve this problem. You are required to add on each side to give inequality b > b + 2z. Now you need to subtract from each side to get 0 > 2z and you can see the correct answer is option (b)

Question 170

If z – q > z + q, then which of the following must be true?

1. 67
2. z < q
3. 5
4. 3 > 9
5. 76

Explanation: Algebraic manipulation can only answer this particular problem. You are required to add o on each side which will bring dissimilarity z > z + 2q. Now you are required to subtract from each side to get 0 > 2q and therefore the answer will be option (b).
