Question

a man bought bananas at the rate of 10 for 45 and sold at the rate of one dozen bananas for 51 find his gain or loss per cent

Answer 1

given:

10 bananas cost= 45

12 bananas cost= 51

now,

10=45$

therefore, 1= 0.23$

&

12= 51$

therefore, 1= 0.24$

change in both rates,

0.24 - 0.23= 0.01$

% gain = (0.01/100* 0.23)

           = 0.000023%

Answer 2

Answer:

55/9

Step-by-step explanation:

C.P. :

10 bananas=45

1 banana=45/10=4.50

S.P. :

12 bananas=51

1 banana=51/12=17/4=4.25

CP>SP : Loss

Loss=4.50-4.25=0.25

Loss %=Loss/CP×100

=0.25/4.5×100

=2.5/45×100

=2.5×20/9

=50/9%=

=5 5/9%
