We have a basket full of papayas, grapes and mangoes. If 55% are papayas and 25% are grapes, then what per cent are mangoes?

Given: Total capacity of basket = 100%

Papayas = 55%

Grapes = 25%

Let mangoes be x%.

Total capacity = Capacity of papayas + Capacity of grapes + Capacity of mangoes 

100 = 55 + 25 + x

⇒ x = 100 − 80

⇒ x = 20%

Therefore, the basket contains 20% of mangoes.
