Question

What price should a shopkeeper mark on a mixer grinder which costs him rupees 2000 so as to gain 5% after allowing an discount of 25% ?​

Answer 1

CP=1200.

To gain 12%, SP=(112/100)*1200=1344.

Now, Marked/Listed price has to set X as to receive a overall profit of 12%, after giving 16% discount.

100–16=88%.

(88/100)*x=1344 | X=1600rs.

To be remembered:

Discount on marked price, gives SP.

Profit/loss is calculated on CP.

Hope it helps.
