   Which organelle is known as the 'powerhouse of the cell' because it produces energy in the form of ATP?

   • A. Ribosomes
   • B. Mitochondria
   • C. Golgi apparatus
   • D. Endoplasmic reticulum

7. Q7 · LCM and HCF

   The HCF of two numbers is 18 and their LCM is 1080. If one number is 108, what is the other number?

   • A. 180
   • B. 162
   • C. 144
   • D. 216
   Answer and solution

   Answer: A

   Using the formula: Product of two numbers = HCF × LCM. So, 108 × other number = 18 × 1080. Other number = (18 × 1080)/108 = 180.

8. Q8 · Simple and Compound Interest

   A sum of money doubles itself in 8 years at simple interest. In how many years will it become triple?

   • A. 16 years
   • B. 12 years
   • C. 20 years
   • D. 24 years
   Answer and solution

   Answer: A

   If principal P doubles in 8 years, the interest = P, so rate = (P × 100)/(P × 8) = 12.5% per annum. To triple, interest needed = 2P. Time = (2P × 100)/(P × 12.5) = 16 years.

9. Q9 · Algebra

   If x² - 5x + 1 = 0, then what is the value of x³ + (1/x³)?

   • A. 110
   • B. 125
   • C. 140
   • D. 155
   Answer and solution

   Answer: A

   From x² - 5x + 1 = 0, we get x + 1/x = 5. Cubing both sides: (x + 1/x)³ = 125 = x³ + 1/x³ + 3(x + 1/x). Therefore x³ + 1/x³ = 125 - 3(5) = 110.

10. Q10 · Trigonometry (Basics)

    If sin θ = 3/5 and θ is acute, then what is the value of (tan θ + cot θ)?

    • A. 25/12
    • B. 37/12
    • C. 41/12
    • D. 49/12
    Answer and solution

    Answer: A

    sin θ=3/5, cos θ=4/5. tan θ=3/4, cot θ=4/3. Sum = 3/4+4/3 = 9/12+16/12 = 25/12.
