Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFযুক্তিটি হল:
কলাম অনুসারে: (2য় সংখ্যা - 1ম সংখ্যা) × 4 = 3য় সংখ্যা
কলাম 1: (15 - 4) × 4 = 11 × 4 = 44
কলাম 3: (21 - 6) × 4 = 15 × 4 = 60
একইভাবে,
ধরি, অনুপস্থিত সংখ্যাটি হল a
কলাম 2: (? - 7) × 4 = 68
⇒ ? - 7 = 68 ÷ 4
⇒ ? - 7 = 17
⇒ ? = 17 + 7
⇒ ? = 24
সুতরাং, '24' সঠিক উত্তর।
