Answer 1

Answer:

40 and 10

Step-by-step explanation:

Let the reciprocal of Aishwaryas age be y

and the reciprocal of Aradhyas age be x

Given

$x + y = \frac{5}{40} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (1)$

$x - y = \frac{3}{40} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (2)$

(1)+(2) Gives

$2x = \frac{5}{40} + \frac{3}{40} = \frac{8}{40} = \frac{1}{5}$

$x = \frac{1}{10}$

(1)-(2) Gives

$2y = \frac{5}{40} - \frac{3}{40} = \frac{2}{40}$

$y = \frac{1}{40}$

Hence age if Aishwarya is 40 and that if Aaradhya is 10
