Venn diagram
CALCULATION:
Players who play exactly one sport = a + b + c = 140
Players who play only football and only hockey = a + b = 75
⇒ Players who play only Cricket = 140 – 75 = 65

Total players who play cricket = 120
∴ Total players play cricket along with at least one more sport = 120 – 65 – 30
= 25
