Answer 2

Given :-

• Chandra bought 10 sheets at rupees 1000 each

• He sold 2 of these at a loss of 20%

Solution :-

Monu bought 10 sheets at a cost of Rs1000 for each set .

Therefore,

Total Cost of sheets = 10 * 1000 = ₹10000

Monu Sold two sheets at a loss of 20%

Therefore,

Selling price of 1 sheet

= 1000 - (20/100)*1000

= 800Rs

Now,

Monu gains overall profit = 5%

= 5/100 * 10000

= Rs500

Total Selling price = 10000 + 500 = Rs10500

Therefore,

Selling price of 8 sheets + Selling price of 2 sheets = 10500

SP of 8 sheets + 2 * 800 = 10500

SP of 8 sheets + 1600 = 10500

SP of 8 sheets = 10500 - 1600

SP of 8 sheets = Rs8900

Now,

The SP of 1 sheet = 8900/8 = Rs1112.5

Hence, Monu should sell the remaining sheet at a cost of Rs1112.5 ..
