19 of the flowers in a flower shop were daffodils,
12 of them were lavenders and the remaining 112 stalks were roses.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers left was 20 less than the number of flowers sold. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were roses
= 1 -
19 -
12 = 1 -
218 -
918 = 1 -
1118 =
718 7 u = 112
1 u = 112 ÷ 7 = 16
Number of stalks of flowers in the shop
= 18 u
= 18 x 16
= 288
(b)
Number of stalks of flowers sold = 1 p + 20
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 20
= 2 p + 20
2 p + 20 = 288
2 p = 288 - 20
2 p = 268
1 p = 268 ÷ 2 = 134
Number of stalks of flowers sold
= 1 p + 20
= 134 + 20
= 154
Answer(s): (a) 288; (b) 154
