In the figure above, (a+b+c)/(s+t+u)=?
সমাধান
সঠিক উত্তর: Option A
Here,
u = a + b
t = a + c
s = b + c
∴ s + t + u = b + c + a + c + a + b = 2(a + b + c)
Here,
(a + b + c)/(s + t + u)
= (a + b + c)/{2(a + b + c)}
= 1/2
u = a + b
t = a + c
s = b + c
∴ s + t + u = b + c + a + c + a + b = 2(a + b + c)
Here,
(a + b + c)/(s + t + u)
= (a + b + c)/{2(a + b + c)}
= 1/2
