Question : Simplify the following: $\frac{\cos x-\sqrt{3} \sin x}{2}$
Option 1: $\cos \left(\frac{\pi}{3}-x\right)$
Option 2: $\sin \left(\frac{\pi}{3}+x\right)$
Option 3: $\cos \left(\frac{\pi}{3}+x\right)$
Option 4: $\sin \left(\frac{\pi}{3}-x\right)$
Correct Answer: $\cos \left(\frac{\pi}{3}+x\right)$
Solution : Given, $\frac{\cos x-\sqrt{3} \sin x}{2}$ = $\frac{1}{2} \cos x-\frac{\sqrt3}{2}\sin x$ = $\cos x \cos \frac{\pi}{3} - \sin \frac{\pi}{3} \sin x$ [$\because\cos \frac{\pi}{3}=\frac{1}{2}$ and $\sin \frac{\pi}{3}=\frac{\sqrt3}{2}$] = $\cos( \frac{\pi}{3}+x)$ Hence, the correct answer is $\cos( \frac{\pi}{3}+x)$.
Question : A sum is deposited in a bank which gives simple interest. The sum becomes 1.25 times in 3 years. If there is a requirement of INR 7,60,000 after seven years, how much amount (in INR) should one deposit to fulfil the requirement?
Option 1: 5,20,000
Option 2: 5,70,000
Option 3: 4,80,000
Option 4: 6,00,000
Correct Answer: 4,80,000
Solution : The sum becomes 1.25 times in 3 years Let the deposit be $P$ ⇒ Interest earned $= 1.25P - P = 0.25P$ According to the formula Simple interest $=\frac{P\times r\times t}{100}$ ⇒ $0.25P =\frac{P\times r ×3}{100}$ ⇒ $r=\frac{100\times 0.25P}{P\times3}$ ⇒ $r = \frac{25}{3}$% There is
Question : Male mosquitoes take their food from
Option 1: human blood
Option 2: standing water
Option 3: sap of plants
Option 4: dung and debris
Correct Answer: sap of plants

Question : A computer program that translates one program instruction one at a time into machine language is called a/an
Option 1: Interpreter
Option 2: Compiler
Option 3: Simulator
Option 4: Commander
Correct Answer: Interpreter
Solution : The correct answer is Interpreter.
An "Interpreter" is a computer programme that interprets one programme command at a time into machine code. Interpreters operate by analysing and executing code line by line, transforming high-level computer instructions into machine code in real time. This is in
Question : The length of the side of a cube is 5.6 cm. What is the volume of the largest sphere that can be taken out of the cube?
Option 1: 91.98 cm3
Option 2: 99.96 cm3
Option 3: 96.98 cm3
Option 4: 90.69 cm3
Correct Answer: 91.98 cm3
Solution : Diameter of the sphere $=$ Edge of the cube ⇒ $2 ×$ radius of sphere $= 5.6$ cm ⇒ The radius of sphere, $r$ $= \frac{5.6}{2} = 2.8$ cm The volume of the sphere $= \frac{4}{3} × π × r^3$ $=\frac{88}{21} × 21.952=91.98$
Question : Directions: In the following question a series is given, with one number missing. Choose the correct alternative from the given ones that will complete the series. 8, 24, 12, ?, 18, 54
Option 1: 48
Option 2: 36
Option 3: 29
Option 4: 21
Correct Answer: 36
Solution : Given: 8, 24, 12, ?, 18, 54
Multiply by 3 and divide by 2 alternatively to get the next term of the series – 8 × 3 = 24; 24 ÷ 2 = 12; 12 × 3 = 36; 36 ÷ 2 = 18; 18
