Question

If 30% is lost by selling a sofa set for Rs 980 at what price must it sold to gain 10%?

Answer 1

Heya...
Here is your answer ---

SP = Rs.980
Loss = 30%
CP = ₹(100/100-L% ×SP)
CP = ₹(100/100-30 ×980)
CP = ₹(100/70 ×980)
CP = ₹(100/7 ×98)
CP = ₹(100×14)
CP = ₹1400

Gain = 10%
SP = ₹(100+G%/100 ×CP)
SP = ₹(100+10/100 ×1400)
SP = ₹(110/100×1400)
SP = ₹(110×14)
SP = ₹1540
