So, had known, is the correct past
Question : The height of an equilateral triangle is $9 \sqrt{3} \mathrm{~cm}$. What is the area of this equilateral triangle?
Option 1: $92 \sqrt{3} \mathrm{~cm}^2$
Option 2: $67 \sqrt{3} \mathrm{~cm}^2$
Option 3: $49 \sqrt{3} \mathrm{~cm}^2$
Option 4: $81 \sqrt{3} \mathrm{~cm}^2$
Correct Answer: $81 \sqrt{3} \mathrm{~cm}^2$
Solution : Let the sides of the equilateral triangle be $a$, then its height = $\frac{a\sqrt3}{2}$ ⇒ $9\sqrt3 = \frac{a\sqrt{3}}{2}$ $\therefore a = 18$ cm Now, the area of the triangle = $\frac{a^2\sqrt3}{4}$ = $\frac{18×18×\sqrt3}{4}$ = $81 \sqrt{3} \mathrm{~cm}^2$ Hence, the correct answer is $81

Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (36, 6, 18) (35, 5, 21)
Option 1: (49, 7, 21)
Option 2: (63, 7, 98)
Option 3: (100, 5, 40)
Option 4: (76, 13, 5)
Correct Answer: (49, 7, 21)
Solution : Given: (36, 6, 18); (35, 5, 21)
In the given sets, multiply the second and third numbers, and then divide the resultant by 3 to get the first number – (36, 6, 18)→6 × 18 = 108; 108 ÷ 3 = 36 (35,
Question : P and Q are centre of two circles with radii 9 cm and 2 cm respectively, where PQ = 17 cm. R is the centre of another circle of radius $x$ cm, which touches each of the above two circles externally. If $\angle PRQ=90^{\circ}$, then the value of $x$ is:
Option 1: 4 cm
Option 2: 6 cm
Option 3: 7 cm
Option 4: 8 cm
Correct Answer: 6 cm
Solution : Given: PQ = 17 cm PR = $(x+9)$ cm RQ = $(x+2)$ cm In right $\triangle$ PRQ By Pythagoras theorem $PQ^2 = PR^2+RQ^2$ ⇒ $17^2 = (x+9)^2+(x+2)^2$ ⇒ $289 = x^2+81+18x+x^2+4+4x$ ⇒ $2x^2+22x-204=0$ ⇒ $x^2+11x-102=0$ ⇒ $x(x+17)-6(x+17)=0$ ⇒ $(x+17)(x-6)=0$ $x = 6$ since $x$
Question : Directions: If A + B means that A is the father of B, A – B means that A is the mother of B, and A × B means that A is the brother of B then which of the following expressions shows that Q is the son of P?
Option 1: P – R × Q
Option 2: Q – P × R
Option 3: P – Q – R
Option 4: P – Q × R
Correct Answer: P – Q × R
Solution : Let's check the given options – First option: P – R × Q According to the given expression, the family tree will be as follows – Here, the quadrilateral represents the male, and the circular figure represents the female. From the
Question : The following table shows the percentage distribution of employees in five different Departments 1 - 5 in a company during the years 2020 and 2021. The total number of employees in 2020 and 2021 is 1200 and 1600, respectively. In which department is the variation in strength of employees maximum in 2021 in comparison to that in 2020?
Option 1: Department 1
Option 2: Department 4
Option 3: Department 5
Option 4: Department 2
Correct Answer: Department 5
Solution : Variation in strength of employees in 2021 in comparison to that in 2020: The number of employees in department 1 in the year 2020 = $\frac{24}{100}\times 1200 = 288 $ The number of employees in department 2 in the year 2020 = $\frac{21}{100}\times 1200
