Totalling each player's row across all five matches gives their overall run tally, which the multiple bar diagram displays match by match.

Step 1 — Draw the multiple bar diagram. For each match (1–5), draw two touching bars — one for Player X, one for Player Y — with a small gap between each match's pair.

Step 2 — Total Player X's runs. $45+20+60+35+50$: $45+20=65$, $65+60=125$, $125+35=160$, $160+50=210$.

Step 3 — Total Player Y's runs. $30+55+40+65+50$: $30+55=85$, $85+40=125$, $125+65=190$, $190+50=240$.

Step 4 — Compare. $210 < 240$, so Player Y scored more overall, by $240-210=30$ runs. …

Comparing only the match where one player scored highest (Player X's 60 in Match 3) rather than totalling every match is a common misreading — a fair comparison of overall perform …
