Question

Let x, y and z are three positive numbers and P = x+y+z ÷2
; if (p-x): (p-y): (p-z) = 3:5:7 then the ratio
of x:y:z is

Answer 1

Hii, your answer is here below⤵

P = x+y+z ÷2

(P-x)=3 [ Putting the value of P]

=>-x+y+z=6-------->(I)

(P-y)=5

=>x-y+z=10-------(II)

(P-z)=7

=>x+y-z=14-------(III)

(I)+(II)+(III),

x+y+z=6+10+14=>30

P = x+y+z ÷2

=>P=30÷2=>15

(P-x)=3

=>x=12

(P-y)=5

=>y=10

(P-z)=7

=>z=8

So, x:y:z=12:10:8

=>6:5:4
