Every week, Mrs Owen collected 60% more vitamin pills than Mrs Sean from the pharmacy. They each consumed 28 vitamins weekly and would leave the rest for their family members to consume the rest. After some time, both ladies consumed a total of 504 vitamin pills and Mrs Owen's family members consumed 756 more vitamin pills than Mrs Sean's family.

1. How many members were there in Mrs Owen's family, if they each consumed 28 pills weekly?
2. How many vitamin pills did Mrs Sean collect from the pharmacy each week?

(a)
60% + 100% = 160%
160% = ¹⁶⁰₁₀₀ = ⁸₅

Number of pills Mrs Sean collected in total = 5 u
Number of pills Mrs Owen collected in total = 8 u

Total pills eaten per week by Mrs Sean and Mrs Owen
= 28 + 28
= 56

Number of weeks
= 504 ÷ 56
= 9

Difference in the number of pills Mrs Owen's family consumed more than Mrs Sean's family
= 8 u - 5 u
= 3 u

3 u = 756

1 u = 756 ÷ 3 = 252

Number of pills that Mrs Owen collected in total
= 8 u
= 8 x 252
= 2016

Number of pills that Mrs Owen's family consumed per week
= 2016 ÷ 9
= 224

Number of members in Mrs Owen's family
= 224 ÷ 28
= 8

(b)
Number of pills that Mrs Sean collected in total
= 5 u
= 5 x 252
= 1260

Number of pills that Mrs Sean collected each week
= 1260 ÷ 9
= 140

Answer(s): (a) 8; (b) 140
