Ans. C | Explanation:
It is given that α + β = - q/p and αβ = r/p, where 0<p<q<r
So, let’s assume p = 1, q = 2 and r = 3.
Putting these values in answer options, we get
(A) 1 / (α + β) = - p/q = - (1/2)
(B) (1/ α) + (1/ β) = (α + β)/ αβ = -(q/p) × (p/r) = - (q/r) = - (2/3)
(C) – 1/ (αβ) = -(p/r) = - (1/3)
(D) αβ/(α + β) = r/p × (-p/q)= - r/q = - (3/2)
We can see that, - (1/3) is the greatest among the above values.

👆Position of Letters in English Alphabet
✍️ Sometimes a word or a sentence is coded by changing the position of English alphabet letters according to a definite pattern, so it is necessary to remember the positions of all the letters in English alphabetical order, both in forward and backward order.

Circular Arrangement of Letters in English Alphabet
If we have to find the letter one placed forward to A, then the letter will be B and this result can be found out by using either linear or circular arrangement but when one is asked to find the letter which is one letter backward of A (Z is one letter backward A) or one letter forward of Z (A is the one letter forward Z), then only circular arrangement gives such results.

👆Angle divisions of a clock👆
🖌A close observation of a clock reveals that an angular space between any two consecutive divisions has further five more divisions. The area between the two divisions corresponds to a value of 5 minutes. Hence, dividing the 30° by five will result in the angular value of a minute.
👉Angular value of a minute = (30°)/5= 6°

Ans. D | Explanation:
Given, Marked price = Rs. 16000
So, Cost Price = (16000/160) × 100 = Rs. 10000
If it is sold at 12% discount, then Selling Price = 16000 × (88/100) = Rs. 14080
Profit on cost price = 14080 - 10000 = Rs. 4080
So, Profit percent = (4080/10000) × 100 = 40.8%
Hence, option (d) is correct.
