The cost of 2 chairs and 3 tables is Rs.1300. The cost of 3 chairs and 2 tables is Rs.1200. The cost of each table is more than that of each chair by__________?
Correct answer: E. None of these
- A. Rs.70
- B. Rs.75
- C. Rs.50
- D. Rs.60
- E. None of these
Explanation
Let a chair cost c rupees and a table cost t rupees. From 2c + 3t = 1300 and 3c + 2t = 1200, solving gives t = 300 rupees and c = 200 rupees, so the difference is 300 rupees - 200 rupees = 100 rupees, which is not listed. The likely trap is option c, 50 rupees, from subtracting the equations without accounting for their different coefficients.

About Linear Equations
Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
