A = 30
B = 25
A∪B = 50
A∩B = ?
A∩B = A + B - A∪B
= 30 + 25 - 50
= 55 - 50
= 5
Hence 5 peopls like both oranges and apple.
Hope it helps!!! :)
Plz batao

Batane keliye kuch nahi hai bhai...voh tho formula based question hai
aapke 11th class textbook zaroor dekega. Formula: A + B = A union B + A intersection B
Intersection ka matlab hai ki jo log dhono pasandh karte.....union total no.of students hai
