Description : Preethi bought 240 reams of brown sheet at Rs 200 per ream and the expenditure on transport Was Rs 960. she had to pay an octroi duty of 1Rs per ream and the labour charges were Rs 120. What should she charge per ream to gain 80%(in Rs)?
Answer :
Total CP= Rs(240*200)=Rs. 48000 Total expenditure=(960+1*240+120)= Rs. 1320 totalCp= 48000+1320=Rs. 49320 gain= 80% sp of 240reams = 49320*180/100 = Rs.88776 Sp per ream= 88776/240= Rs 369.9
