Question

Answer

At first

A -> 5u

B -> 234 – 5u

After transfer 2/5 of A to B

A -> 5u – 2u = 3u

B -> 234 – 5u + 2u = 234 – 3u

Given: A had 24 more than B

3u – 24 = 234 – 3u

6u = 258

u = 43

At first, B had (234 – 5u) = 234 – 215 = 19

Check

A -> 215

B ->  19

2/5 of A -> 2/5 × 215 = 86

In the end

A -> 215 – 86 = 129

B -> 19 + 86 = 105

129 – 105 = 24
