The following table shows the different number of items a shopkeeper sold with different cost prices and different selling prices. Use this information to match the items of List A with the items of List B.

The correct match for i, ii, iii is

For 

100 items. : Profit=(14-10)100=400.

200 items: profit=(12.5-9.5)200=600.

300 items: profit=(11-9)300=600.

400 items: profit=(10-8)400=800.

500 items: profit=(9-7.5)500=750.

600 items: profit=(7.5-7)600=300.

700 items: profit=(6.5-6)700=350.

So, profit for 800 items is maximum.

So, i will go with a.

if selling price is increased by 1 ,then profit for 100 items become=(15-10)100=500.

This is the minimum profit for the ii condition.

So,ii will go with b.

if no conditions are given then,

profit for 600 items will be minimum which incurs only 600(6.5-6)=300.

So, iii will go with c.

So, i,ii and iii will go with a,b and c.

A is correct choice.
