ReplyDeletepls how to slove 6th?
ReplyDelete6) there is 20% decrease so 20% of 36 is 7.2.
ReplyDeleteIn 7.2rs he is getting 500gms. In 36rs he will get 500/7.2*36=2500gms=2.5kg.
It means he was getting 2 kg before, so ans is 18.
Old value=(R/100+-R)*unit price/extra value
Delete=(20/80)*36/1/2=>18
Original price = [contact price /{increased amount fraction =more quantity})
ReplyDeleteQuestions 2.
Contact value 500 gram
Increase in amount = 1/4
It means that
1/4=500 gram
So total quantity is 2000 gram or 2 kg
Original value formula
Constant value /total quantity
36/2= 18 per kg
