A shop had 256 more curry puffs than sardine puffs at first.

After selling \( {1\over 4}\) of the curry puffs and \( {2\over 3}\) 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?

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)

         \( {256 + S \over 4} + {25 \over 3} = 121\)
         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$
