¶¶helo¶¶thank you dear for asking questions and plz don't delete the answer because I am not copy to google.ok

SP of 1 kg of apple = Rs 40 and loss % = 10%

So CP = {100/(100-L%)} x 40 = (100/90) x 40 = Rs 400/9.

So, loss in Rs = CP - SP = 400/9 - 40 = Rs 40/9.

If the loss is Rs 40/9, qty of apples sold = 1 kg.

If the loss is Rs 120, qty of apples sold = 120/(40/9) = 120 x 9/40 = 27.

So, quantity of apples sold is 27 kg.
