110 of the flowers in a flower shop were roses,
14 of them were orchids and the remaining 247 stalks were marigolds.
- How many stalks of flowers were there in the shop?
- At the end of the day, the number of flowers sold was 16 more than the number of flowers left. How many stalks of flowers were sold?
(a)
Fraction of stalks of flowers that were marigolds
= 1 -
110 -
14 = 1 -
220 -
520 =
1320 13 u = 247
1 u = 247 ÷ 13 = 19
Number of stalks of flowers in the shop
= 20 u
= 20 x 19
= 380
(b)
Number of stalks of flowers sold = 1 p + 16
Number of stalks of flowers left = 1 p
Total number of stalks of flowers
= 1 p + 1 p + 16
= 2 p + 16
2 p + 16 = 380
2 p = 380 - 16
2 p = 364
1 p = 364 ÷ 2 = 182
Number of stalks of flowers sold
= 1 p + 16
= 182 + 16
= 198
Answer(s): (a) 380; (b) 198
