Answer 1

Answer:

not sure but may be 280 . I have just thought

Answer 2

Answer:

A) 490

Step-by-step explanation:

As per question....

let first part be- x

therefore 2nd part = y

and 3rd pary = z

now 4x=5y and 4x=7z

x+y+z=1162

y=4/5(x) , z=4/7(x)

x+4/5(x)+4/7(x) =1162

(35x+28x+20x)/35=1162

83x=1162*35=40670

x=40670/83

=490
