The total number of fruits altogether are 504 fruits.
An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the total number of fruits, hence:
Number of papayas = (3/8)x
Number of apples = (5/7)[x - (3/8)x]
Number of guavas = x - (5/7)[x - (3/8)x] - (3/8)x = x - (5/7)(5/8)x - (3/8)x
90 = x - (5/7)[x - (3/8)x] - (3/8)x
x = 504
The total number of fruits altogether are 504 fruits.
