alleryએક કાફેમાં 150 મુલાકાતીઓ આવ્યા હતા. 25 લોકોએ કોફી અને ચા બંને લીધા, 40 લોકોએ ફક્ત ચા લીધી અને 60 લોકોએ ફક્ત કોફી લીધી. કેટલા લોકોએ આમાંથી કંઈપણ ન લીધું?
A15
B20
C35
D25
Answer & Solution
Correct answer: D. 25
ઉપયોગમાં લેવાયેલા ત્રણ ભાગોનો કુલ સરવાળો 60 + 25 + 40 = 125 થાય છે, જેથી બંને વર્તુળોની બહાર 150 - 125 = 25 રહે છે.
