If \(\frac{x}{5} = \frac{y}{8}\), then (x + 5) : (y + 8) is equal to:
সমাধান
সঠিক উত্তর: Option D
Solution:
|
ধরি,\(\frac{x}{5} = \frac{y}{8}\) = k \(\frac{x}{5} = k\) => x = 5k x + 5 = 5k + 5 |
এবং \frac{y}{8}\)= k => y = 8k y + 8 = 8k + 8 |
অতএব, (x + 5) : (y + 8) = 5k + 5 : 8k + 8 = 5 (k + 1) : 8 (k + 1) = 5 : 8 |
