Question
In a certain code, SAM is written as 917 and ENTHUSE is
written as 2634892. In this coding system, which of the following could be a possible code for the word ENTHUSIASM?Solution
The pattern followed here is: Logic: Every alphabet is coded with unique number. SAM is written as 917 Here, code of S → 9 A → 1 M → 7 And, ENTHUSE is written as 2634892 Here, code of E → 2 N → 6 T → 3 H → 4 U → 8 S → 9 E → 2 Similarly, ENTHUSIASM is written as '? E → 2 N → 6 T → 3 H → 4 U → 8 S → 9 I → A → 1 S → 9 M → 7
I. x2 – 3(x + 5) = -11
II. y2 – 4(y + 2) = -2y
I. 9/(4 )p + 7/8p = 21/12
II. 7/5p = 9/10q + 1/4

II. 2y2 + 13y + 21 = 0
I. p2 - 53p + 672 = 0
II. q2 - 27q + 126 = 0
I. 8x2 - 2x – 15 = 0
II. 12y2 - 17y – 40 = 0
l). 2p² + 12p + 18 = 0
ll). 3q² + 13q + 12 = 0
I. 63x² + 146x + 80 = 0
II. 42y² + 109y + 70 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 24x + 143 = 0
Equation 2: y² - 26y + 165 = 0
Solve the quadratic equations and determine the relation between x and y:
