Question

solve this question I will mark as brain list

Answer 1

She sold 45 pens that month
this means she made a profit of 45*2= Rs. 90
but 
As per Question she made a loss of Rs. 10
=> she made a total loss of 90-x=-10
                                           x=Rs. 100
it is given that she incurs a loss of 50 paise per pencil
=> She sold 100÷1/2
                     = 100×2=200
Therefore she sold 200 pencils that month
