      Solution

      ATQ,

      Let the income of 'S' be Rs. '100n'

      Income of 'R' = 1.25 × 100n = Rs. '125n'

      Expenditure of 'R' = 0.55 × 125n = Rs. '68.75n'

      Expenditure of 'S' = 0.7 × 100n = Rs. '70n'

      So, 70n – 68.75n = 525

      Or, 1.25n = 525

      Or, n = 420

      Savings of 'R' = 125n – 68.75n = 56.25n = 56.25 × 420 = Rs. 23,625
