64% of the fruits at a stall are oranges. The rest are apples and pears in the ratio 4:5. There are 880 more oranges than pears. How many fruits are there at the stall altogether?

This is similar to the other problem.....the apples and pears comprise the other 36%...and if they're in the ratio of 4:5  .....  there must be  16% apples and 20% pears.....

Again, let T be the total....and we know that

.64T = .20T + 880    subtract .20T   from both sides

.44T  = 880      divide both sides by .44

T = 880/.44  = 2000 total fruits

Check  .....there are .64 x 2000 = 1280 oranges

And there are .20  x 2000 = 400  pears

And (1280 - 400)  = 880
