C.)
Let the time taken by computer for virus scan be, 'x' days
We are given that Computer A runs a virus scan in every 2.75 days and Computer B runs a virus scan in every 3.5 days.
<h3>Amount of work done by computer A⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
<h3>Amount of work done by Computer B⤵️</h3>
Amount of work done in one day = 
Amount of work done in x days = 
Since, They are doing the same work the amount of work done is 1.

Solve for x ~






➪ <em>Thus, the time taken when both computers run a virus scan at the same time again is, 1.54 days</em>
