16 of the flowers in a flower shop were daffodils,
14 of them were roses and the remaining 140 stalks were lilies.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers sold was 18 more than the number of flowers left. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were lilies
= 1 -
16 -
14 = 1 -
212 -
312 =
712 7 u = 140
1 u = 140 ÷ 7 = 20
Number of stalks of flowers in the shop
= 12 u
= 12 x 20
= 240
(b)
Number of stalks of flowers sold = 1 p + 18
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 18
= 2 p + 18
2 p + 18 = 240
2 p = 240 - 18
2 p = 222
1 p = 222 ÷ 2 = 111
Number of stalks of flowers sold
= 1 p + 18
= 111 + 18
= 129
Answer(s): (a) 240; (b) 129
