Quantitative Section : Quantitative Ability

Given below are a few important questions on Multiple Choices with answers and explanation. Select the right answer from the following questions.

1. If z(g) = |g| + 20 for which of the following values of g does z(g) = z(-g)?

1. 15 f
2. 18x
3. All real g
4. 10 except x
5. 10x

Explanation: To start with the equation the statement z(g) = z(-g) when z = -20 and 20. A simple number like zero works best. z(0) = Ι0Ι + 20 = 20. You can see that z(0) = z(-0) so zero must be the part of correct answer, therefore (c) is the correct option.

2. If q/c = 0.595, then c/q is equal to which of the following?

1. 34/7
2. 2.67
3. 12.01
4. 7/5
5. 32.87

Explanation: Make the base on both sides of the equation the same. 243 is similar as 45. So 45x = 45,which means that x = 1

3. If u - 5 = 5 (1 - u), then what is the value of u?

1. 0.33
2. 2.78
3. 9.45
4. 8.45
5. 6.45

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

4. The distance between the points (-7, 5) and (-7, -18) is

1. 32/6
2. 23.98
3. 7.8
4. 25
5. 12.98

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

5. If t/n = 0.455, then t/n is equal to which of the following?

1. 9.67
2. 2.67
3. 5.78
4. 0.45
5. 6.45

Explanation: Make the base on both sides of the equation the same. 673 is similar as 85. So 85x = 85,which means that x = 1. Therefore the correct option would be (b)

6. If m - 4 = 4 (1 - m), then what is the value of m?

1. 0.33
2. 56
3. 43.09
4. 43.98
5. 43/89

Explanation: The fraction j/p is a reciprocal of p/c. To find the numerical value of j/p, just flip the numerical value of p/j, which is 0.625. Your calculation will tell you that 1/0.625 = 0.33.

7. If 9c + 2d = 11 and z - 3d = 5, then what is the value of z?

1. 45/7
2. 32.45
3. 45/3
4. 9.45
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 d term leaving you with the equation 8c = 16, so z = 2

8. What is the slope of the line given by the equation 3w - 8 = 7 - 2z?

1. - 43
2. - 2/3
3. 3/5
4. 8
5. 23/4

Explanation: To find the slope of the line without difficulty, get its equation into the form w = zc + d, where m will be the value of the slope. To express 3w - 8 = 7 - 2m in this form, just isolate n. You will find that w = -2/4 + 4. Here the slope of the line (z) is - 2/4

9. If v(o) =2o2+ 2 then what is the value of v(o + 4)?

1. 7v2+8
2. 2h2 + 6
3. 4y2+ b +43
4. 6g2+ 12 +56
5. 2x2+ 16x +34

Explanation: Assume that o = 3. We are trying to find v(3 + 4) = v(7) = 2(7)2 + 2 which is 100 our target number. Now insert 3 in for o in the answer choices to see which answer choice goes with the target its (e)

10. If w = log, (wx) then pz =

1. 25p
2. fx
3. 45w
4. 13y
5. w

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