Neave had 383 coins less than Ivory. Given that they have a total of 689 coins,
- How many coins did Ivory have?
- How many coins did Neave have?
(a)
Number of coins that Ivory had = 1 u
Number of coins that Neave had = 1 u - 383
Total number of coins
= 1 u + 1 u - 383
= 2 u - 383
2 u - 383 = 689
2 u = 689 + 383
2 u = 1072
1 u = 1072 ÷ 2 = 536
Number of coins that Ivory had
= 1 u
= 536
(b)
Number of coins that Neave had
= 1 u - 383
= 536 - 383
= 153
Answer(s): (a) 536; (b) 153
