Selling price of the item,SP =Rs990

loss per cent , loss% = 10%

Cost price of the item, CP=...............

Note :

We have the formula to find CP , When SP and loss% is given ,

i.e. CP= 100100-loss%×SP .

So,

CP =100100-10×990

CP= 10090×990

CP=9900090 ( divide 99000 by 90, we get 1100)

CP=1100.

Therefore, the answer for the given blank is Rs1100.
