Let me use "•••" to represent 1 unit for Muthu's marbles and the symbol "|" to separate the units for Abdul's 5 units.
DAN | ••• | ••• | ••• | ••• | ••• (total: 328)
DAN | ••• (total: 176)
You can see that the difference between the two will be ••• | ••• | ••• | •••, which is basically 4 units as reflected in your actual model on the paper.
4 units = 328 - 176
4 units = 152
1 unit = 38
So, Muthu has 38 marbles.
But Muthu and Dan has 176 marbles.
Dan's marbles
= 176 - 38
= 138
DAN | ••• | ••• | ••• | ••• | ••• (total: 328)
DAN | ••• (total: 176)
You can see that the difference between the two will be ••• | ••• | ••• | •••, which is basically 4 units as reflected in your actual model on the paper.
4 units = 328 - 176
4 units = 152
1 unit = 38
So, Muthu has 38 marbles.
But Muthu and Dan has 176 marbles.
Dan's marbles
= 176 - 38
= 138
