take prod of 10 person be x..
so of 11 people it will be 1.1x.. and 12 people=1.1x*1.1=1.21x..
I still dont understand the 12pep part..
Q says, 10% increase by one number increase then for 12pep isnt it suppose to be,
could you please explain me how you came up with dividing by 1.1??!!
hi ..if with each person increased , prod increases by 10%... 1.1x*0.1
gives you the increase,which is 10% of the prod of 11 people but to get total we have to add these incr to prod of 11 person =1.1x+.11x=1.21x..
