Kelvin and Daniel had an equal number of paper clips at first. After Kelvin gave away 17 paper clips and Daniel gave away 5 paper clips, Daniel had 5 times as many paper clips as Kelvin, Hie many paper clips did Daniel have at first?

Let Kelvin and Daniel have \(x\) paper clips at first. 

 

Now, no. of paper clips left - 

With Kelvin = \(x-17\)

With Daniel = \(x-5\)

 

According to question, 

\(x-5 = 5(x-17)\)

\(x-5 = 5x -85\)

\(4x = 80\)

\(x=20\)

 

∴ Daniel had 20 paper-clips at first.
