Study Notes
Coke as a Fuel
- Coke is the purest form of carbon.
- It burns efficiently and provides maximum energy.
Profit Percentage Calculation
- If 7 articles are sold for the cost price of 9, the profit is calculated as follows:
- Cost price (CP) of 9 articles = ₹9 (assuming ₹1 per article)
- Selling price (SP) of 7 articles = ₹9
- SP of 9 articles = (9/7) * 9 = ₹81/7
- Profit = (81/7) - 9 = ₹18/7
- Profit percentage = (18/7) * 100 ≈ 257%
Family Relationships
- A, B, C, D, E, F, and G are family members.
- There are two doctors, two teachers, two professors, and one lawyer.
- No female is a teacher or lawyer.
- The teacher's wife is a professor, and the lawyer's wife is also a professor.
- C is F's daughter-in-law and E's mother.
- B (a doctor) is G's son. E (not a professor) is the lawyer's daughter.
- A's husband is a teacher; A is C's mother-in-law and B's grandmother.
- F is B and D's grandfather.
- D is A's grandson.
Hexagonal Seating Arrangement
- Six people (A, B, C, D, E, F) sit in a hexagon.
- A is not next to B or C.
- D is not next to C or E.
- B and C are adjacent.
- F is between D and C.
- One possible arrangement is B, C, F.
Circular Seating Arrangement
- Seven people sit in a circle.
- G is second to the left of C, who is to the immediate left of F.
- B is between D and E.
- A is third to the left of E.
- The order is D, B, E.
- F's position is fourth to the right of D, to the immediate right of C, between C and E, and second to the right of A
Carbon Dioxide and Litmus Paper
- Carbon dioxide dissolves in water.
- The resulting solution turns blue litmus paper red.
- This indicates the formation of an acid (carbonic acid).
Star Rotation and Polaris
- Stars appear to rotate east to west due to Earth's rotation.
- Polaris (the North Star) is an exception because it's located almost directly above the Earth's North Pole.
Cooking Utensil Handles
- Cooking utensil handles are made of Bakelite because it's a poor conductor of heat and electricity.
Natural and Synthetic Fibers
- Polyester is a synthetic fiber, not a natural fiber.
Pressure and Area
- Pressure is force per unit area.
- If the area increases and the force remains constant, the pressure decreases.
Yeast and Dough Rising
- Yeast in dough produces carbon dioxide during respiration.
- The carbon dioxide gas causes the dough to rise.
