The number of curry puffs at first is repeated. Make the number of curry puffs at first the same. LCM of 3 and 6 is 6.
Number of puffs left
= 1 u + 2 u - 182
= 3 u - 182
3 u - 182 = 1
35 u
3 u - 1
35 u = 182
1
25 u = 182
1 u = 182 ÷ 1
25 = 130
Total number of puffs that Anna sold
= 5 u + 182
= 5 x 130 + 182
= 650 + 182
= 832
Answer(s): 832
