Answer / pushpendra ahirwar
It's correct answer is 40 years.
16 gm to 8 gm in 10 years
8 gm to 4 gm in 10 years {again}
4 gm to 2 gm in 10 years
2 gm to 1 gm in 10 years
So, It will take {10+10+10+10=40} 40 years.

Answer / valarmathy
16 gm reduced to 8gm in 10yrs
so 8 gm get decayed
for decaying 1 gm it takes 10/8 yrs
for decaying 8 gm it takes 10/8*8
remaining 8 gm
need to decay 7 to get 1 gm remaining
for decaying 7 it takes
10/8*8*7
=10*7
=70 years
