Draw the structure of the product of this reaction.
. this is favored 3-methyl cyclo hex-3-ene.
Reactant is presentin chair conformer. since methyl and bromo groups are present trans to each other and methyl group at equatorial position is more stable axial, the bromo group is forced to equatorial position. Now bromine is a good leaving group.
and trans elimination is favorable over syn elimination.
Hence The major product is the one given above
