Answer with Step-by-step explanation:
Six pencils are equal in value to two rulers.
i.e. Value of 6 pencils=Value of 2 rulers
Value of 6×2 pencils=Value of 2×2 rulers
Value of 12 pencils=Value of 4 rulers ----------(1)
One ruler is equal in value to two erasers.
i.e. Value of 1 ruler=Value of 2 erasers
Value of 1×4 rulers=Value of 2×4 erasers
Value of 4 rulers=Value of 8 erasers ---------(2)
By equation (1) and (2), we get
Value of 12 pencils = Value of 8 erasers
Hence, Twelve pencils are equal in value to eight erasers
