Yoko was packing her bowls, spoons and plates to be moved to her new shop. She packed 85 more bowls than spoons, and 60 more plates than bowls. While moving
25 of her bowls and
110 of the spoons were broken. The remaining 371 items were not broken. How many plates did she have?

5x2 =
10 u |
+ 85 |
10 u |
10 u |
+ 85 + 60 |

- 2x2 =
- 4 u |
- 34 |
- 1 u |

|
After |
3x2 =
6 u |
+ 51 |
9 u |
10 u |
+ 145 |
371 |
25 x 85 = 34
LCM of 5 and 10 is 10.
Total number of items that was not broken
= 6 u + 51 + 9 u + 10 u + 145
= 25 u + 196
25 u + 196 = 371
25 u = 371 - 196
25 u = 175
1 u = 175 ÷ 25 = 7
Number of plates that Yoko had
= 10 u + 145
= 10 x 7 + 145
= 70 + 145
= 215
Answer(s): 215
