Vaidev had 225 erasers more than Min. Given that they have a total of 497 erasers,
- how many erasers did Min have?
- how many erasers did Vaidev have?
(a)
Number of erasers that Vaidev that = 1 u + 225
Number of erasers that Min had = 1 u
Total number of erasers
= 1 u + 225 + 1 u
= 2 u + 225
2 u + 225 = 497
2 u = 497 - 225
2 u = 272
1 u = 272 ÷ 2 = 136
Number of erasers that Min had
= 1 u
= 136
(b)
Number of erasers that Vaidev had
= 1 u + 225
= 136 + 225
= 361
Answer(s): (a) 136; (b) 361
