Question : The longest side of the obtuse triangle is 7 cm and the other two sides of the triangle are 4 cm and 5 cm. Find the area of the triangle.
Option 1: $1 \sqrt{3} \mathrm{~cm}^2$
Option 2: $6 \sqrt{3} \mathrm{~cm}^2$
Option 3: $3 \sqrt{2} \mathrm{~cm}^2$
Option 4: $4 \sqrt{6} \mathrm{~cm}^2$
Correct Answer: $4 \sqrt{6} \mathrm{~cm}^2$
Solution : Given triangle is an obtuse triangle as $7^2 > 4^2 + 5^2$. Semi perimeter of the triangle($s$) = $\frac{7+4+5}{2}$ = 8 cm $\therefore$ Area of the triangle = $\sqrt{8(8-7)(8-4)(8-5)}$ = $\sqrt{8×(1)×(4)×(3)}$ = $\sqrt{96}$ = $\sqrt{16×6}$ = $4\sqrt{6} \mathrm{~cm}^2$ Hence, the correct answer is
Question : Directions: Marks of five girls Mansi, Kajal, Reetu, Tina, and Riya are compared. Marks of Riya is less than Mansi but more than Tina. Marks of Reetu are less than Tina, Riya, and Mansi. Marks of Kajal are less than Reetu. Marks of how many girls are less than the marks of Tina?
Option 1: 2
Option 2: 1
Option 3: 4
Option 4: 3
Correct Answer: 2
Solution : Given: (I) Marks of Riya is less than Mansi but more than Tina. Mansi > Riya > Tina (II) Marks of Reetu are less than Tina, Riya, and Mansi. Marks of Kajal are less than Reetu. After combining all the statements – Mansi > Riya
Question : Select the appropriate antonym for the underlined word.
The tension is going to be crucial in determining the fate of your company.
Option 1: surgical
Option 2: decisive
Option 3: trivial
Option 4: pivotal

Question : Directions: Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. 121 : 145 :: 169 : 197 :: 256 : ?
Option 1: 325
Option 2: 280
Option 3: 290
Option 4: 288
Correct Answer: 290
Solution : Given: 121 : 145 :: 169 : 197 :: 256 : ?
Add 1 to the square root of the first number. Then find the square and add 1 to get the second number. 121 : 145→√121 = 11; (11 + 1)2 + 1
Question : The larger diagonal of a rhombus is 150% of its smaller diagonal, and its area is 432 cm2. Find the length (in cm) of the side of the rhombus.
Option 1: $8 \sqrt{13}$
Option 2: $4 \sqrt{13}$
Option 3: $6 \sqrt{13}$
Option 4: $2 \sqrt{13}$
Correct Answer: $6 \sqrt{13}$
Solution : Given: The larger diagonal of a rhombus is 150% of its smaller diagonal, and its area is 432 cm2. Let the length of the smaller diagonal be $x$ cm. The length of the larger diagonal = 150% of $x=\frac{3x}{2}\ \text{cm}$ We know,
