Two computers just scanned for viruses at the same time. Computer A runs a virus scan every 2.75 days. Computer B runs a virus s
Elis [28]

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 = \tt\frac{1}{2.75}

Amount of work done in x days = \tt\frac{x}{2.75}

<h3>Amount of work done by Computer B⤵️</h3>

Amount of work done in one day = \tt\frac{1}{3.5}

Amount of work done in x days = \tt\frac{x}{3.5}

Since, They are doing the same work the amount of work done is 1.

\sf \:  \frac{x}{2.75}  +  \frac{x}{3.5}  = 1

Solve for x ~

\sf \frac{x}{ \frac{11}{4} }  +  \frac{x}{ \frac{7}{2} }  = 1

\sf \frac{4x}{11}  +  \frac{2x}{7}  = 1

\sf \: 28x + 22x = 77

\sf \: 50x = 77

\sf \: x =  \frac{77}{50}

\boxed{ \bf \: x = 1.54}

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