Question : Directions: Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation. 32 * 42 * 7 * 7 * 17 = 202
Option 1: ×, ÷, –, +
Option 2: ×, –, +, ÷
Option 3: +, ÷, ×, –
Option 4: +, ×, ÷, –
Correct Answer: ×, ÷, –, +
Solution : Given: 32 * 42 * 7 * 7 * 17 = 202
Let's check the given options – First option: ×, ÷, –, + ⇒ 32 × 42 ÷ 7 – 7 + 17 = 202 Solving the L.H.S. of the equation

Option 2: Milton Friedman
Option 3: Irving Fisher
Option 4: James Duesenberry
Correct Answer: Irving Fisher
Solution : The correct answer is Irving Fisher.

Question : Directions: In the following question, select the related letters from the given alternatives. NA : SF :: OB : ?
Option 1: IJ
Option 2: TG
Option 3: RG
Option 4: TH
Correct Answer: TG
Solution : Given: NA : SF :: OB : ?
Add 5 to the place value of each letter of the given term, to obtain the required term – Like, NA : SF→N + 5 = S; A + 5 = F Thus, NA is coded as
Question : Directions: If A – B means that A is the mother of B, A + B means that A is the father of B, and A ÷ B means that A is the sister of B, then which of the following expressions shows that P is the aunt of Q?
Option 1: P + R ÷ Q
Option 2: Q ÷ R + P
Option 3: P ÷ R – Q
Option 4: R ÷ P – Q
Correct Answer: P ÷ R – Q
Solution : Given: A – B ⇒ A is the mother of B A + B ⇒ A is the father of B A ÷ B ⇒ A is the sister of B
Let's check each option – First option: P + R

Question : If $a+b=1$, then $a^4+b^4-a^3-b^3-2a^2b^2+ab$ is equal to:
Option 1: 1
Option 2: 2
Option 3: 4
Option 4: 0
Correct Answer: 0
Solution : Given: $a+b=1$ (equation 1) We know that the algebraic identities are $(a-b)^2=a^2+b^2-2ab$, $(a^3+b^3)=(a+b)(a^2-ab+b^2)$ and $(a^2-b^2)=(a+b)(a-b)$. So, $a^4+b^4-2a^2b^2-a^3-b^3+ab$ $=(a^2-b^2)^2-(a^3+b^3)+ab$ $=(a+b)^2(a-b)^2-(a+b)(a^2-ab+b^2)+ab$ Substituting the value from equation 1 in the above expression we get, $a^4+b^4-2a^2b^2-a^3-b^3+ab=(a-b)^2-a^2+ab-b^2+ab$ $=(a-b)^2-(a^2-2ab+b^2)$ $=(a-b)^2-(a-b)^2=0$ Hence, the correct answer is 0.
Question : Directions: In the question, a part of the sentence is in bold. Below are given alternatives to the bold part at (1), (2), and (3) that may improve the sentence. Choose the correct alternative. In case no improvement is needed, your answer is (4).
