Answer 1

lemons rs 24 /dozen gives each lemon cost price is rs 2
sells at a rate of 4 for rs 12 then each lemon selling price is 12/4=3 ,rs 3
from the above he gains in selling the lemons and gain=s.p-c. p
=36-24=12
he gains rs 12 .

mark it as brainliest answer

Answer 2

CP OF 12 LEMONS =24 Rs
CP OF 1 LEMON = 24/12
= 2 RS
TOTAL LEMONS BROUGHT = 12
SP OF 4 LEMONS = 12
SP OF 1 LEMON = 12/4
= 3 Rs
SP OF 12 LEMONS = 12×3
=36 Rs
SINCE SP>CO IT'S A GAIN
PROFIT = SP-CP
=36-24
12 Rs
Therefore gain% = profit/cp×100
= 12/24×100
=50%
