Eva and Hazel have $247. Usha and Eva have $327. The ratio of Hazel to Usha is 1 : 5. How much does Eva have?
Amount that Hazel has = 1 u
Amount that Usha has = 5 u
The amount that Eva has is the repeated identity.
Eva + 1 u = 247 --- (1)
Eva + 5 u = 327 --- (2)
(2) - (1)
5 u - 1 u = 327 - 247
4 u = 80
1 u = 80 ÷ 4 = 20
From (1):
Eva + 1 u = 247
Eva + 1 x 20 = 247
Eva + 20 = 247
Amount that Eva has
= 247 - 20
= $227
Answer(s): $227
