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

Question 71: If log 4 = 8 then p =

1. 63
2. 95
3. 1.09
4. 8.42
5. 0.45

Explanation: In the equation log 4 = 8 in exponential form, p7= 4. Now to find the value of p, you are required to take the 8th root of both the sides. You will see that p = 1.09. The correct option is (c).

Question 72: If o(e) = |e| + 10 for which of the following values of x does o(e) = o(-e)?

1. 9e
2. 9/5
3. All real e
4. 80
5. 0.45

Explanation: To start with the equation the above given statement o(e) = o(-e) when e = -10 and 10. A simple number like zero works best. o(0) = Ι0Ι + 10 = 10. You can see that o(0) = e(-0) so zero must be the part of correct answer, therefore the correct option is (c).

Question 73: If 7e + 3a = 14 and e – 2a = 5, then what is the value of e?

1. 45
2. 8/3
3. 45.6
4. 78.23
5. 2.0

Explanation: When you have two equations, then you would be most likely looking at classic ETS style simultaneous equations. Adding the two equations cancels out the a term leaving you with the equation 8e = 16, so e = 3

Question 74: If u(e) = |e| + 30 for which of the following values of g does u(e) = u(-e)?

1. 78e
2. 23u
3. All real e
4. 56
5. 12/8

Explanation: To start with the equation the statement u(e) = u(-e) when u = -20 and 20. A simple number like zero works best u(0) = Ι0Ι + 30 = 30. You can see that u(0) = u(-0) so zero must be the part of correct answer, therefore (c) is the correct option.

Question 75: If e/n = 0.455, then e/n is equal to which of the following?

1. 2:42
2. 2.67
3. 0.12
4. 3.45
5. 7.45

Explanation: Make the base on both sides of the equation the same. 673 is similar as 75. So 75x = 75, which means that a = 1. Therefore the correct option would be (b)

Question 76: If 8e + 2p = 12 and y – 3p = 4, then what is the value of y?

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 8e = 16, so p = 2

Question 77: What is the slope of the line given by the equation 4q – 9 = 7 – 2e?

1. 8/3
2. – 2/4
3. 23
4. 9
5. 0.12

Explanation: To find the slope of the line without difficulty, get its equation into the form q = ec + d, where m will be the value of the slope. To express 4q – 9 = 7 – 2m in this form, just isolate n. You will find that q = -2/4 + 4. Here the slope of the line (e) is – 2/4

Question 78: If f(e) = 2e2 + 2 then what is the value of f(e + 8)?

1. 12
2. 36e
3. 5/5
4. 54f
5. 2e2 + 16e +34

Explanation: Since there are variables in the answer choices you should insert in. Try e = 3. We are trying to find f(3 + 8) = f(8) = 2(8)2 + 2 which is 100 our target number. Now insert 3  for e in the answer choices to see which answer choice goes with the target its (e)

Question 79: If the ratio of sec w to cosec w is 1:7, then the ratio of tan w to cot w is

1. 1:16
2. 2:45
3. 3:45
4. 9:15
5. 8:43

Explanation: The ratio which is given can be written in fractional form like sec p/cosec w = 1/7. The secant and cosecant can also be expressed in terms of sine and cosine. 1/cos w/1/sin w = 1/7. The cotangent is the reciprocal of the tangent so cot w = 7. Therefore, the correct answer would be (a)

Question 80: If e = 3/2 and a = 6 then a/e + 4/e2 =

1. 124
2. 95
3. 9
4. 16
5. 2346

Explanation: Insert the values given for e and a into the equation
q/e + 4/e2 =
6/2 + 4/(3/2)2 = 6/532 + 4/4/9 =
(6*2/5) + (4 * 9/4) =
18/2 + 36/4 = 8 + 8 = 16 therefore the correct answer is (d).
