Question : Each member of a club contributes an amount in rupees and paise equal to the number of members in the club. If the total contribution is Rs. 2525, then what is the number of members in the club?
Option 1: 60
Option 2: 45
Option 3: 55
Option 4: 50
Correct Answer: 50
Solution : Let the number of members be $x$. So each member contributes $x$ rupees and $x$ paise. According to the given information, $x × x + x × \frac{x}{100}= 2525$ ⇒ $x^2 + \frac{x^2}{100} = 2525$ ⇒ 101$x^2= 252500$ ⇒ $x^2= 2500$ ⇒ $x = 50$
Question : What is the value of (a + b)3 – a3 – b3?
Option 1: – 3ab(a – b)
Option 2: 3ab(a + b)
Option 3: – 3ab(a + b)
Option 4: 3ab(a – b)
Correct Answer: 3ab(a + b)
Solution : (a + b)3 – a3 – b3 = a3 + b3 + 3ab(a + b) – a3 – b3 = 3ab(a + b) Hence, the correct answer is 3ab(a + b).
Question : A is 20% more efficient than B. How much time will they working together take to complete a job which A alone could have done in 29 days?
Option 1: $\frac{145}{11}$ days
Option 2: $\frac{116}{11}$ days
Option 3: $\frac{203}{11}$ days
Option 4: $\frac{174}{11}$ days
Correct Answer: $\frac{174}{11}$ days
Solution : According to the question, The efficiency of A is 20% more than that of B Let the efficiency of B be 100% $\therefore$ The efficiency of A = 120% of the efficiency of B ⇒ Efficiency of A = $\frac{6}{5}$ of efficiency of B
Question : If in $\triangle PQR$ and $\triangle DEF, \angle P=52^{\circ}, \angle Q=74^{\circ}, \angle R=54^{\circ}, \angle D=54^{\circ}, \angle E=74^{\circ}$ and $\angle F=52^{\circ}$, then which of the following is correct?
Option 1: $\triangle \mathrm{PQR} \sim \triangle \mathrm{FED}$
Option 2: $\triangle \mathrm{RQP} \sim \triangle \mathrm{FED}$
Option 3: $\triangle \mathrm{PRQ} \sim \Delta \mathrm{FED}$
Option 4: $\triangle \mathrm{PQR} \sim \triangle \mathrm{DEF}$
Correct Answer: $\triangle \mathrm{PQR} \sim \triangle \mathrm{FED}$
Solution : $\because$ $\angle P=\angle F=52^0$ $\angle Q=\angle E=74^0$ And $\angle R=\angle D=54^0$ By AAA criteria, triangles are similar. So, $\triangle \mathrm{PQR} \sim \triangle \mathrm{FED}$. Hence, the correct answer is $\triangle \mathrm{PQR} \sim \triangle \mathrm{FED}$.
