Given, Ashish's monthly income is Rs.9600. His monthly expenditure is 60% of his income.

His monthly expenditure is 9600× 100__60[Upon] =5,760.

Now, his monthly savings is 9,600−5,760=3,840

Let the CP of 1 pen be Rs x

Then,

CP of 14 pens will be 14×x=14x

And

CP of 14 pens=SP of 10 pens

Hence,

SP of 10 pens =14x

Then,,

SP of 1 pen=14x÷10=1.4x

Gain=SP−CP.=1.4x−x=Rs0.4x

Gain(%)= CP__gain[Upon] ×100

= x__0.4x [Upon]×100=40%

Gain= 40%
