question number 12,13,14,15 very urgently solve this question

Answer 1

Answer:

Step-by-step explanation:

Q12.)40 dozen bananas = 480 bananas

30 bananas rotten = 480 - 30 = 450 bananas left

thus, cp of 40 dozen bananas = rs 250

to make 205 profit sp of 450 bananas

=250*120/100 = rs 300

thus sp of 1 banana = 300/450 = rs2/3

sp of dozen bananas = 2/3*12

                                   =rs 8

Q13.)C.P of 10 eggs = rs 8

Therefore, CP of 1 egg = 8/10 = 4/5

S.P of 8 eggs = rs 10

And, S.P of 1 egg = 10/8 = 5/4

Therefore, profit = S.P - C.P

=5/4 - 4/5

=(25 - 16)/20

=9/20

So,profit % = (9/20)÷4/5 x 100

=(9/20) x (5/4) x 100

=225/4 %

=56.25 %

Q14.) cost price of oranges is given as Rs.26/-per dozen

seling price of 5 oranges =Rs.13

therefore,selling price of oranges= 13/5

seling price of 12 oranges =13/5×12=Rs.31.20 per dozen

seling price of oranges >cost price of oranges

so,gain occurs

gain on selling a dozen of oranges=S.P - C.P.=31.20 -26=5.20

GAIN%=gain / C.P ×100 =5.2/26  ×100=52/260 × 100=20%    

                   there fore, the required gain % is =20%

Q15.) Cp of 6 toffees = rs. 1  

Cp of 1 toffee = rs. 1/6  

Gain = 20%  

Sp of 1 toffee = 1/6 x 120/100 = 1/5  

So for rs. 1 he should sell 5 toffees
