Hence, the fourth option is correct.
Question : Directions: Which two signs and two numbers (Not digits) of the equation should be interchanged to make it correct? 13 × 12 ÷ 36 + 11 – 7 = 35
Option 1: + and ×, 36 and 7
Option 2: + and –, 12 and 7
Option 3: × and ÷, 13 and 36
Option 4: × and ÷,11 and 7
Correct Answer: × and ÷,11 and 7
Solution : Given: 13 × 12 ÷ 36 + 11 – 7 = 35
Let's check the given options – First option: + and ×, 36 and 7 13 × 12 ÷ 36 + 11 – 7 = 35 On interchanging the mathematical
Question : Which among the following is the correct relationship between geometric length Lg and magnetic length Lm?
Option 1: Lm = 6/5 * Lg
Option 2: Lm = Lg
Option 3: Lm = 2 RY
Option 4: Lm = 5/6 Lg
Correct Answer: Lm = 5/6 Lg
Solution : The correct answer is Lm = 5/6 * Lg.
The magnetic length is the distance between the two poles of the magnet, and the geometric length is the actual length of the magnet. This implies that the magnetic length is 5/6
Question : Directions: In the following question, find the odd number from the given alternatives.
Option 1: 12
Option 2: 24
Option 3: 80
Option 4: 48
Correct Answer: 80
Solution : Let's check the options – First option: 12; 12 × 1 = 12 Second option: 24; 12 × 2 = 24 Third option: 80; 80 is not a multiple of 12. Fourth option: 48; 12 × 4 = 48
Hence, the third option is correct.
Question : Directions: A piece of paper is folded and punched as shown below in the question figure. From the given answer figures, indicate how will it appear when opened.
Solution : When the paper is unfolded, the following figures will be obtained –
Hence, the first option is correct.
Question : Directions: If K means subtracted from, L means divided by, M means added to and D means multiplied by, then 96 L 4 K 6 M 11 D 9 = ?
Option 1: 117
Option 2: 125
Option 3: 120
Option 4: 145
Correct Answer: 117
Solution : Given: 96 L 4 K 6 M 11 D 9 = ?
On replacing the letters with the mathematical signs, the equation becomes – = 96 ÷ 4 – 6 + 11 × 9 = 24 – 6 + 11 × 9 = 24 –
Question : Directions: In a certain code language, MOCK is coded as 9326, MINK is coded as 2538, LUNE is coded as 5041, and LOUT is coded as 6714. What can be the code for ONM in that code language?
Option 1: 649
Option 2: 653
Option 3: 567
Option 4: 658
Correct Answer: 653
Solution : Given: 1. MOCK ⇒ 9326 2. MINK ⇒ 2538 3. LUNE ⇒ 5041 4. LOUT ⇒ 6714
By comparing all the three coded words, we find that – In words 1 and 2 the common letter is M/K and the common code is 3/2.
Question : Which of the following is not a play written by Shakespeare?
Option 1: Antony and Cleopatra
Option 2: The Comedy of Errors
Option 3: The Candle Stand
Option 4: Othello
Correct Answer: The Candle Stand

Question : What happens when one S and one P orbital are hybridized?
Option 1: We get three orbitals in a plane
Option 2: We get two orbitals at 180 degrees
Option 3: We get two mutually perpendicular orbitals
Option 4: We get four orbitals directed tetrahedrally
Correct Answer: We get two orbitals at 180 degrees
Solution : The correct option is We get two orbitals at 180 degrees
Hybrid orbitals produced by the hybridization of S and P orbitals are applicable for chemical bonding. Depending on the quantity and kind of orbitals involved, a hybrid of
Question : Who, in the 1860s, undertook a thorough investigation of the gas laws expressing the relationships of pressure, temperature and volume in carbon dioxide?
Option 1: Thomas Andrews
Option 2: Giulio Natta
Option 3: John Dalton
Option 4: Marguerite Perey
Correct Answer: Thomas Andrews
Solution : The correct answer is Thomas Andrews.
Thomas Andrews, an Irish chemist and physicist, conducted a thorough investigation of the gas laws, focusing on the relationships between pressure, temperature, and volume in carbon dioxide. Andrews' work on carbon dioxide in the 1860s was significant in
