Question : The average of 5 numbers is 48. The average of the two numbers is 40 while the average of the other two is 58. Find the value of the remaining number.
Option 1: 44
Option 2: 34
Option 3: 40
Option 4: 30
Correct Answer: 44
Solution : The total sum of the 5 numbers = (48 × 5) = 240 The sum of the two numbers = (40 × 2) = 80 The sum of the other two = (58 × 2) = 116 So, the value of the remaining number =
Question : In which element group of the periodic table are fluorine, chlorine, bromine and iodine included?

(1) So hoarse he was
(2) that he could not make
(3) the speech.
(4) No Error
Option 1: 1
Option 2: 2
Option 3: 3
Option 4: 4
Correct Answer: 1
Solution : The original sentence has the word order reversed. In English, we typically use the word order "subject + verb + adjective/adverb" instead of "adjective/adverb + subject + verb." Therefore, the correct word order is "He was so hoarse," which makes the sentence grammatically correct.
Question : The sum of three positive numbers is 18 and their product is 162. If the sum of two numbers is equal to the third number, the sum of the squares of the numbers is:
Option 1: 120
Option 2: 126
Option 3: 132
Option 4: 138
Correct Answer: 126
Solution : Let the three positive numbers be $x, y,$ and $z$. The sum of three positive numbers, $x + y + z = 18$--------- (1) The product of the three numbers, $x × y × z = 162$---------------------- (2) Given that the sum of two numbers
Question : One angle of an isosceles obtuse triangle is $28 \frac{1}{2}^{\circ}$. Find the measure of its obtuse angle in degrees.
Option 1: $132^{\circ}$
Option 2: $112^{\circ}$
Option 3: $121^{\circ}$
Option 4: $123^{\circ}$
Correct Answer: $123^{\circ}$
Solution : One of the angles of obtuse-angled isosceles triangle is $\frac{57}{2}^\circ$, the other same angle will be $\frac{57}{2}^\circ$. Let the obtuse angle be $x$. Thus, the sum of angles of a triangle $=180^\circ$ ⇒ $\frac{57}{2}+\frac{57}{2}+x=180^\circ$ ⇒ $\frac{114}{2}+x=180^\circ$ ⇒ $57+x=180^\circ$ ⇒ $x=123^\circ$ So, the measure of its
