19% of the fruits at a stall are oranges. 23% of them are pears. 28% of them are apples and the remaining 180 fruits are mangoes. Find the total number of fruits in the stall?
(19 + 23 + 28)% = 70% of the fruits are something other than mangoes.
Then, mangoes must comprise the other 30%.......let N be the total numer of fruits....so.....
180 = 30% of N ..... or ......
180 = .30N divide both sides by .30
180/.30 = N = 600 total fruits
