Question
In the question below, a sentence is given with four
words highlighted in bold. One or more than one of these four words may be either wrongly spelt or inappropriate in the context of the sentence. Find out the word(s), which is/are wrongly spelt or inappropriate, if any. If all the words are correctly spelt and appropriate in the context of the sentence, choose 'All are correct' as your answer. Psycologists(A) want to understand how the human mind is extraordinary(B) among animal minds and where the unique expects(C) of human minds and behaviours(D) come from.Solution
Word A has been incorrectly spelt. The correct word is "psychologists" ("persons who specialize in the study of mind and behaviour or in the treatment of mental, emotional, and behavioural disorders"). Word C is inappropriately used in the sentence. The verb "expects" cannot be modified by the adjective "unique". It needs to be replaced with the noun "aspects" ("parts or features of something") as an adjective can modify the nouns only. Other words are correctly spelt and used appropriately in the sentence. Hence, option b) is the answer. Extraordinary: very unusual or remarkable.
l. x2 - 16x + 64 = 0
II. y2Â = 64
I. 14p² + 9p - 8 = 0
II. 4q² - 19q + 12 = 0
I. 22x² - 97x + 105 = 0
II. 35y² - 61y + 24 = 0
 If 4x = 40, 3y = 33, what is the value of 6x + 4y?
I. 17x² - 26x – 16 = 0
II. 17y²- 26y + 9 = 0
Equation 1: x² - 144x + 5184 = 0
Equation 2: y² - 130y + 4225 = 0
I. 20y² - 13y + 2 = 0
II. 6x² - 25x + 14 = 0
- Suppose both the roots of q² + kq + 49 = 0 are real and equal, then determine the value of 'k'.
I. x2 – 36 = 0
II. y2 - 7y + 6 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 29x + 210 = 0
Equation 2: y² - 27y + 182 = 0
