A shop had 256 more curry puffs than sardine puffs at first.
After selling 14 of the curry puffs and 23 of the sardine puffs, there were
377 more curry puffs than sardine puffs left.
(a) How many curry puffs were there at the shop at first?
(b) The sardine puffs were sold at $1.30 each. How much was collected
from selling the sardine puffs?
+129 C = No. of curry puffs = 256 + 5
S = No. of sardines puffs = S
We have, C - S = 256 ---- (1)
(C - C/4) + (S - 25/3) = total available stock
C/4 + 25/3 = total sold-out stock
Total sold eat = 377 - 256 = 121
∴ C/4 + 25/3 = 121 --- (2)
∴ Solving (1) and (2)
C = 256 + S put in (2)
256+S4+253=121
S = 62.181 ~ 63
∴ C = 319.
(a) Total curry puffs = 319.
(b) Profits by selling S = 63/3 * 2 = 42.
∴ 42 * 1.3$ = 54.6$
