Hi! I'm am confused and do not know the solution to this word problem. Can you solve it?

This is the word problem:

Mrs Pang sells pineapples, honeydews and papayas. 0.25 of the fruits are pineapples and 0.4 of the remaining fruits are honeydews. If there are 75 more papayas than honeydew, how many fruits are there in Mrs Pang's fruit stall?

Thank you.

change all decimals/percentage to fractions --> 0.25 = 1/4, 0.4 = 2/5

Mrs Pang sells pineapples, honeydews and papayas. 1/4 of the fruits are pineapples and 2/5 of the remaining fruits are honeydews. If there are 75 more papayas than honeydew, how many fruits are there in Mrs Pang's fruit stall?

Pineapples : Honeydews + Papayas --> 1 : 3, Honeydews : Papayas --> 2 : 3 (**total 5)

Pineapples : Honeydews+Papayas : Honeydews : Papayas
= 5 : 15 : 6 : 9 (**equalize the total for honeydews + papayas)
--> Total 20u, Papayas --> 9u, Honeydews --> 6u
3u --> 75, 1u --> 25, 20u --> 500

500 fruits in total

cheers.
