I. x2 – x – 42 = 0,
II. y2 – 17y + 72 = 0 to solve both the equations to find the values of x and y?

A. If x < y (Correct)
B. If x > y
C. If x ≤ y
D. If x ≥ y
E. If x = y or the relationship between x and y cannot be established.

Explanation:

I. x2 – 7x + 6x – 42 = 0
=> (x – 7)(x + 6) = 0 => x = 7, -6
II. y2 – 8y – 9y + 72 = 0
=> (y – 8)(y – 9) = 0 => y = 8, 9
=> x < y

General Knowledge, MCQs / Q&A /
Mostly bank notes in the world are made of what?

A. Cotton  (Correct)
B. Paper
C. Cellulose
D. Wood

Banknotes are generally made of cotton paper. Sometimes cotton is mixed with linen, abaca or other types of fibres to increase its life. The paper used is more durable than everyday paper which makes it resistant to wear and tear.
