There are some rabbits and peacocks in a zoo. The total number of their heads is 60 and total number of their legs is 192. Find the number of total rabbits?
Correct answer: E. None of these
- A. 30
- B. 46
- C. 40
- D. 44
- E. None of these
Explanation
Let rabbits be r and peacocks be p, both counts of animals. From r + p = 60 and 4r + 2p = 192, doubling the first equation gives 2r + 2p = 120; subtraction gives 2r = 72, so r = 36 rabbits. A likely mistake is option b, 46, caused by assigning the wrong number of legs to one type of animal.

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.
