total rupees =90

18x=90

X = rupees/ sum of age

prerna =10*5 =50

Answer 2

Arnav get's 40 and Prena get's 50

Step-by-step explanation:

Arnav = 8yrs

Prena = 10yrs

8 : 10 = 4 : 5

Then,

Arnav get's:

$= \frac{4}{4 + 5} \times 90 \\ = \frac{4}{9} \times 90 \\ = 40$

Prena get's:

$= \frac{5}{4 + 5} \times 90 \\ = \frac{5}{9} \times 90 \\ = 50$
