Answer 2

Answer:

6

Step-by-step explanation:

let each time he bought 12 bananas

c.p of 1 banana at 3 for 1

= 1/3 & c.p of 1 banana at 2 for 1 = 1/2

total c.p of 24 bananas

= 12*1/3 + 12*1/2 = Rs 10

c.p of 1 dozen bananas with two different rates = 10/2 = Rs 5

required s.p to gain 20%

= 5 + 20% of 5 = Rs 6
