​

Answer 1

Answer:

8

Step-by-step explanation:

Correct option is

Rs. 8

C.P. of bananas =Rs.250, Gain required=20%

∴ S.P. of bananas =

100

250×120

=Rs. 300

Number of good bananas =(40×12−30)=450

∴ S.P. of 450 bananas=Rs. 300

⇒ S.P. of 12 bananas = Rs.

450

300

×12=Rs. 8

∴ The remaining bananas should be sold at Rs. 8 per dozen to make a profit of 20%
