Q7 of 59 Page 147

On selling apples at 40 per Kg, a vendor incurs 10% loss. If he incurs a total loss of ₹ 120, calculate the quantity (in Kg) of apples he sold.

Given: SP = ₹40 per kg, total loss =₹120


Loss% = 10


Let the total quantity be x kg


CP = SP + Loss


⇒ CP = 40x + 120..(1)



⇒


⇒ CP = ₹ 1200


Putting in (1),


⇒ 40x + 120 = 1200


⇒ 40x = 1080


⇒ x = 27


Total quantity = 27 kg
