1.a shopkeeper buys an article at rs 150 and sells it at a profit of 12 percentage .find the selling price ?

Rs.168

Step-by-step explanation:

here,

cp=Rs.150

profit=12percentage

sp=cp+profit percentage*cp

=150+12/100*150

=168

so,selling price is Rs.168

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
