Pair of Linear Equations in Two Variables: Class 10 Mathematics (गणित) (Bihar Board) important questions and practice
Pair of Linear Equations in Two Variables is chapter 3 of 14 in Bihar Board Class 10 Mathematics (गणित). Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Graphical representation and nature of solutions
- Conditions for consistent, inconsistent and dependent pairs
- Substitution method
- Elimination method
- Word problems on ages, speed, fractions and two-digit numbers
What examiners usually ask
- Solve graphically: x + y = 5 and 2x - y = 4, and find the area of the triangle formed with the x-axis
- For what value of k does the pair kx + 3y = k - 3, 12x + ky = k have no solution?
- A boat goes 30 km upstream and 44 km downstream in 10 hours; find the speed of the boat and the stream
Exam tip
Memorise the three ratio conditions (a1/a2, b1/b2, c1/c2) for unique, no and infinite solutions, since the 'value of k' question appears nearly every year and is lost by applying the wrong inequality.
