Question

a man buys 144 oranges for 360 and sell them at gain 10% at what rate dozen he sell them ​

Answer 1

Answer:

Step-by-step explanation:

Total gain = C.P + 10% of CP

⇒  360+ 360  (10/100)

⇒ 360 + 36

⇒396

now , he sells 144 oranges for 396 rupees

144→396

12×12→396

as 1 dozen = 12,  transposing 12 to other side of equation,

12→396/12

12→33

∴ the man sells a dozen at 33 rupees.
