Question

4.
If x+y, yuz, z+x are in the ratio 6:7:8 and x + y + z =14 then the value of x is
(a) 6
(b) 7
(c) 8
(d) 10​

Answer 1

Answer:

b)7

Step-by-step explanation:

x+y: y+z :z+x is 6:7:8

x+y+z=14

x=???

Answer 2

Step-by-step explanation:

x+y, y+z, z+x are in the ratio 6:7:8

x + y = 6k

y+z = 7k

z + x = 8k

adding all

2(x + y + z) = 21k

x + y + z = 14

2×14 = 21k

k =4/3

y+ z = 7k = 28/3

x + y + z =14

x + 28/3 =14

x =14/3

y= 10/3

z =6
