Sarah was packing her spoons, plates and bowls to be moved to her new shop. She packed 90 more spoons than plates, and 49 more bowls than spoons. While moving
25 of her spoons and
110 of the plates were broken. The remaining 443 items were not broken. How many bowls did she have?

5x2 =
10 u |
+ 90 |
10 u |
10 u |
+ 90 + 49 |

- 2x2 =
- 4 u |
- 36 |
- 1 u |

|
After |
3x2 =
6 u |
+ 54 |
9 u |
10 u |
+ 139 |
443 |
25 x 90 = 36
LCM of 5 and 10 is 10.
Total number of items that was not broken
= 6 u + 54 + 9 u + 10 u + 139
= 25 u + 193
25 u + 193 = 443
25 u = 443 - 193
25 u = 250
1 u = 250 ÷ 25 = 10
Number of bowls that Sarah had
= 10 u + 139
= 10 x 10 + 139
= 100 + 139
= 239
Answer(s): 239
