Question : Directions: 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 the 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 03,10, etc., and P can be represented by 55, 67, etc. Similarly, you have to identify the set for the word REST
Option 1: 96, 33, 44, 87
Option 2: 58, 21, 85, 75
Option 3: 89, 40, 31, 56
Option 4: 77, 10, 5, 68
Correct Answer: 58, 21, 85, 75
Solution : Here, from the matrices (Matrix 1 and Matrix 2) we get the numbers that represent the letters of the word REST –
R→58, 65, 77, 89, 96 E→02, 14, 21, 33, 40 S→59, 66, 78, 85, 97 T→56, 68, 75, 87, 99
Question : If $AD, BE$ and $CF$ are medians of $\triangle ABC$, then which of the following statement is correct?
Option 1: $(AD + BE + CF) > (AB + BC + CA)$
Option 2: $(AD + BE + CF) < (AB + BC + CA)$
Option 3: $(AD + BE + CF ) = (AB + BC + CA)$
Option 4: $(AD + BE + CF ) = \sqrt2(AB+BC+CA)$
Correct Answer: $(AD + BE + CF) < (AB + BC + CA)$
Solution : Here, $AB+AC>2AD$ ---------------(1) $AB+BC>2BE$ -------------------(2) $BC+AC>2CF$ -------------------(3) By adding equation (1), (2), and (3), we get, $2(AB+BC+AC)>2(AD+BE+CF)$ $⇒(AB+BC+AC)>(AD+BE+CF)$ Hence, the correct answer is $(AD + BE + CF) < (AB + BC + CA)$.
Question : The line chart given below shows the savings and expenditures of 5 companies.
Income = Saving + Expenditure Which of the following sequences is correct about the income of companies A, B, C, D, and E?
Option 1: B > E > C > A > D
Option 2: E > B > C > D > A
Option 3: B > E > C > D > A
Option 4: E > B > C > A > D
Correct Answer: E > B > C > D > A
Solution : To determine the income of each company, Add the savings and expenditures together for each company. Company A: 400 (300 saving + 100 expenditure) Company B: 1200 (800 saving + 400 expenditure) Company C: 900 (600 saving

Question : The value of $\frac{\cos65^\circ}{\sin25^\circ}+\frac{\cos55^\circ}{\sin35^\circ}-\tan50^\circ\cot50^\circ$ is equal to:
Option 1: 2
Option 2: 0
Option 3: –1
Option 4: 1
Correct Answer: 1
Solution : Given: $\frac{\cos65^\circ}{\sin25^\circ}+\frac{\cos55^\circ}{\sin35^\circ}-\tan50^\circ\cot50^\circ$ = $\frac{\cos65^\circ}{\sin(90^\circ-65^\circ)}+\frac{\cos55^\circ}{\sin(90^\circ-55^\circ)}-\tan50^\circ\frac{1}{\tan50^\circ}$ = $\frac{\cos65^\circ}{\cos65^\circ}+\frac{\cos55^\circ}{\cos55^\circ}-1$ = $1+1-1$ = $1$ Hence, the correct answer is 1.
