35 Victoria's money =
25 Usha's money
610 Victoria's money =
615 Usha's money
Victoria's money : Usha's money = 10 : 15
(3) = (4)
50 u - 12 = 30 u - 2.2
50 u - 30 u = 12 - 2.2
20 u = 9.8
1 u = 0.49
Amount Usha has at first
= 15 u
= 15 x 0.49
= 7.35 (a)
Amount Victoria has in the end
= 10 u - 2.4
= (10 x 0.49) - 2.4
= 2.5 (b)
Answers: (a) $7.35; (b) $2.50
