In one mitotic division, 2 daughter cells are formed from 1 parent cell.
In 3 generations, no.of cells will be 2³ = 8.

50% of the cells again undergo 4 generations of mitosis.
50% cells = 8×(50/100) = 4 cells
cells not undergoing division = 8-4 = 4
in 4 mitotic division, number of cells produced from 4 cells = 4×2⁴ = 4×16 = 64

total cells = 64+4 = 68

:)
they go four more generations? wait....isnt it gonna go through just one more extra mitosis? o_O
" 'again' undergo four generations of mitosis" - not 4th generation
ooohhhh......tnx ^-^
