Answer 2

let the cost price of the fan be ' x '

Given loss = ₹40

selling price of the fan = ₹710

since , he suffered loss ,so then

Find the cost price:
--------------------------

cost price - loss = selling price

x - ₹40 = %= ₹710 => x = ₹710 + ₹40

x = ₹750

cost price of the fan = ₹750

given he should sold it on 10 % gain .then

Find the gain:
------------------

required gain = 10% = 10% of cost price

= 10% of 750 = 0.1 × 750 = ₹75

Find the new selling price:
------------------------------------

new selling price=cost price+required gain

= ₹750 + 75 = ₹825

Answer: he should sell the fan for ₹825 to gain 10% on it .
