Q1. Midpoint formula is the section formula with ratio (NCERT):
- A.3:1
- B.2:1
- C.1:0
- D.1:1
Answer: D. 1:1
Q2. The point dividing (1,2)-(7,8) in ratio 1:2 is (NCERT):
- A.(3, 4)
- B.(5, 6)
- C.(4, 5)
- D.(2, 3)
Answer: A. (3, 4)
Data from the problem: 1; 2; 7; 8; 1. We need: the unknown asked in the stem. Key equation - hence the required answer = (3, 4). This is the equation that links the given quantities to the unknown (math, chapter 'Coordinate Geometry'). Putting the numbers in: hence the required answer = (3, 4). Why this works - set up the relation specified by the stem (formula / theorem from the relevant Class-10 chapter) and substitute the listed numerical data. So the answer is A) (3, 4). Wrong options at a glance: option B) '(5, 6)' fails since ((1.7+2.1)/3, (1.8+2.2)/3) = (3,4); option C) '(4, 5)' is wrong because It is (3, 4).
Q3. The centroid divides each median in ratio (NCERT):
- A.2:1 from the vertex
- B.1:3
- C.3:1
- D.1:1
Answer: A. 2:1 from the vertex
