Answer: (d)- 1.76 kg

Step-by-step explanation:

Given

The first laptop mass was 11 kg

The rate of mass decreases by 4.7% per year

In 1982, it was

$\Rightarrow 11-11\times 4.7\%=11-11\times 0.047\\\Rightarrow 11(1-0.047)\ kg$

In 1983, it was

$\Rightarrow 11(1-0.047)-11(1-0.047)\times 0.047=11(1-0.047)^2$

In 2019 i.e. after 38 years, it is

$\Rightarrow 11(1-0.047)^38=11\times 0.953^{38}=1.76\ kg$
