Number of meiosis required to produce 102 pollen grains is

A number of meiosis required to produce 102 pollen grains is 26.
Meiosis division leads to the formation of 4 daughter cells, therefore a pollen grain on meiotic division produces 4 pollen grains.
Thus, 25 pollen grains produce 100 new pollen grains, but according to the question, the required number of pollen is 102, therefore 26 meiotic divisions will produce the required number of pollen grains.
