Question : Find the exact value of $\cos 120^{\circ}$.
Option 1: –0.5
Option 2: 0
Option 3: 0.5
Option 4: 1
Correct Answer: –0.5
Solution : We know that, $\cos (90^\circ + \theta) = - \sin \theta$ So, $\cos 120^\circ = \cos (90^\circ + 30^\circ) = - \sin30^\circ =-\frac{1}{2} = -0.5$ Hence, the correct answer is –0.5.

Question : What value of $y$ will satisfy the following equation? $\frac{3 y}{1+\frac{1}{1+\frac{y}{1–y}}} = 2$
Option 1: $\frac{2}{3}$
Option 2: $\frac{5}{4}$
Option 3: $\frac{4}{5}$
Option 4: $\frac{3}{2}$
Correct Answer: $\frac{4}{5}$
Solution : Given: $\frac{3 y}{1+\frac{1}{1+\frac{y}{1–y}}} = 2$ ⇒ $\frac{3 y}{1+\frac{1–y}{1}} = 2$ ⇒ $\frac{3 y}{2–y} = 2$ ⇒ $3y = 4–2y$ ⇒ $5y = 4$ ⇒ $y = \frac{4}{5}$ Hence, the correct answer is $\frac{4}{5}$.
Question : Directions: Select the odd group of numbers. (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.)
Option 1: 14 – 193
Option 2: 15 – 220
Option 3: 16 – 251
Option 4: 17 – 284
Correct Answer: 14 – 193
Solution : Let's check the options – First option: 14 – 193; 142 – 5 = 191 ≠ 193 Second option:15 – 220; 152 – 5 = 220 Third option: 16 – 251; 162 – 5 = 251 Fourth option:17
Question : The mass number of potassium is:
Option 1: 39
Option 2: 40
Option 3: 38
Option 4: 37
Correct Answer: 39
Solution : The correct option is 39.
Since potassium (symbol K) has several isotopes, the mass number of potassium can change. Atoms of the same element that differ in their neutron counts but have the same number of protons, which characterises the elements, are called isotopes.
Question : $\triangle$ XYZ is a right-angled triangle and $\angle$Y = 90° If XY = 2.5 cm and YZ = 6 cm, then the circumradius of $\triangle$XYZ is:
Option 1: 6.5 cm
Option 2: 3.25 cm
Option 3: 3 cm
Option 4: 2.5 cm
Correct Answer: 3.25 cm
Solution : Given: XYZ is a right-angled triangle and $\angle$Y = 90°, where XY = 2.5 cm and YZ = 6 cm. Let the hypotenuse of the triangle be $h$ cm. So, $h^2=6^2+(2.5)^2$ ⇒ $h=\sqrt{42.25}$ ⇒ $h=6.5$ cm We know, The circumradius of a right-angled triangle
