Question : Which among the following is not a characteristic of transition metals?
Option 1: Tendency to gain electrons
Option 2: Low electronegativity
Option 3: Low ionization energy
Option 4: Malleablity
Correct Answer: Tendency to gain electrons
Solution : The correct option is Tendency to gain electron

Question : Directions: Select the option in which the numbers share the same relationship in the set as that shared by the numbers in the given set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g.13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (12, 144, 1728) (6, 36, 216)
Option 1: (11, 121, 1000)
Option 2: (14, 196, 2197)
Option 3: (10, 100, 1000)
Option 4: (8, 64, 729)
Correct Answer: (10, 100, 1000)
Solution : Given: (12, 144, 1728); (6, 36, 216)
Here, (12, 144, 1728)→(12)2 = 144; (12)3 = 1728 (6, 36, 216)→(6)2 = 36; (6)3 = 216
Let's check each option – First option: (11, 121, 1000)→(11)2 = 121; (11)3

Question : The point $R(a,b)$ is first reflected over the origin to $R_1$ and $R_1$ is reflected over the X-axis to (–4, 2). The coordinates of point $R$ are:
Option 1: (–4, –2)
Option 2: (–4, 2)
Option 3: (4, 2)
Option 4: (4, –2)
Correct Answer: (4, 2)
Solution : Given: The coordinates of the point $R(a,b)$ reflected over the origin are $R(–a,–b)$. The coordinates of $R(–a,–b)$ are reflected over the X-axis to $(–a, b)$. But $(–a, b)$ $=(–4, 2)$ So, $a=4,b=2$ Thus point R (4, 2) Hence, the correct answer is (4, 2).
