`SP = ((100 - loss%)) /100 X CP`

CP = 100/((100+ g a i n %)) xx SP

If CP = Rs. 100 and loss = Rs. 20, then SP = Rs. 80.

S.P.= M.P.((100-Discount %)/(100))

In case of gain, S.P. =((100+"gain"%)xxC.P.)/(100) . (True/False)

Marked price = (100 xx S.P.)/100 - ........ %) .Then the blank space is filled by :

If S.P of an article is Rs 8000 and loss is 1/5 of its C.P then find C.P.

If S.P.=₹ 900 and loss=25%, then C.P. is

Find the gains or loss per cent when:(1)CP=₹2400 and SP =2592 (2)CP= ₹1650 and ₹1452 (3) CP =₹12000 and SP =₹12800 (4) CP= ₹1800 and SP =₹1611
