Answer 2

Answer:

Explanation:

Solution :

Old Ratio =

Neetu: Seetu : Keetu = 3:5:7

After,

Keetu retires :

Keetu's share taken by Neetu =

$\frac{7}{15} \times \frac{3}{5} = \frac{21}{75}$

Keetu's share taken by Seetu =

$\frac{7}{15} \times \frac{2}{5} = \frac{14}{75}$

Keetu's new Share =

$\frac{3}{15} + \frac{21}{75} = \frac{15 + 21}{75} = \frac{36}{75}$

Seetu's new Share =

$\frac{5}{15} + \frac{14}{75} = \frac{25 + 14}{75} = \frac{39}{75}$

Keetu : Seetu =

$\frac{36}{75} : \frac{39}{75}$

$36 : 39$ = 12 : 13

Therefore, Option = 12 : 13

the new ratio will be: Keetu : Seetu = 12 : 13
