Option 1: 5 : 3
Option 2: 3 : 4
Option 3: 3 : 2
Option 4: 8 : 5

Solution : According to the question, For company A, Sales in 2019 = 12500 units Sales in 2020 = 10625 units X is the percentage decrease in the number of units ⇒ X = $\frac{12500 - 10625}{12500}\times 100 = 15$% Also, for company B, Sales
Question : If $\left (a+\frac{1}{b} \right)=1$ and $\left (b+\frac{1}{c} \right)=1$, the value of $\left (c+\frac{1}{a} \right)$ is:
Option 1: 0
Option 2: 1
Option 3: – 1
Option 4: 2
Correct Answer: 1
Solution : Given: $a+\frac{1}{b}=1$ and $b+\frac{1}{c}=1$ ⇒ $a =1-\frac{1}{b}=\frac{(b-1)}{b}$ ⇒ $\frac{1}{a}=\frac{b}{(b-1)}=\frac{-b}{(1-b)}$ Also, $b+\frac{1}{c}=1$ ⇒ $\frac{1}{c} =1-b$ ⇒ $c = \frac{1}{(1-b)}$ Now, $c + \frac{1}{a}$ $=\frac{1}{(1-b)}-\frac{b}{(1-b)}$ $=\frac{(1-b)}{(1-b)}$ $= 1$ Hence, the correct answer is 1.
Question : Direction: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. 'A' can be represented by 02, 14, etc and 'O' can be represented by 55, 67, etc. Similarly, you have to identify the set for the word 'LEND'
