Question

komoloka was thrice as old as seela 6 years back. Komoloka will be five-thirds times as old as Seela 6 years hence. How old is Seela today?​

Answer 1

Answer:

Seela's present age is 12 years

Step-by-step explanation:

let Komoloka's present age be 'x' and Seela's 'y'

$x - 6 = 3(y-6) => equation 1\\x+6 = \frac{5}{3} (y+6) => equation2 \\equation2 - equation1 \\x + 6 - x + 6 = \frac{5}{3}y - 3y + \frac{5}{3} (6) + 18 \\12 = \frac{5-9}{3} y + 28 \\12 = \frac{-4}{3} y + 28 \\\frac{4}{3} y = 28-12 = 16\\4y = 16*3 = 48 \\y = \frac{48}{4} = 12$
