A computer takes 50 nanoseconds to do an addition. How many additions can it do in 1 second?
Solution
Correct Answer: Option C
We know,
I nanosecond =10⁻⁹) s
50 " =(50× 10⁻⁹)s
=(50× 10× 10⁻⁹)s
=5× 10⁻⁸ s
The computer adds in 5× 10⁻⁸ =1 calculation
" " : 1s =1/(5× 10⁻⁸)=10⁸/5
=2×10⁸/5×2
=2×10⁸/10
=2×10⁷=2 crores
=20 million
[1 crore =10 million]
