alleryABCD ক'ডে 1–6 সুকীয়া সংখ্যা ব্যৱহাৰ কৰে। C=2D আৰু A+C=B+D। দুটা অংকৰ সংখ্যা AB আৰু CD ৰ পাৰ্থক্য 24, AB ডাঙৰ। A×C+B×D বিচাৰি উলিয়াওক।
A13
B11
C15
D17
Answer & Solution
Correct answer: A. 13
C=2D ৰাখিলে B=A+D পোৱা যায়।
তাৰ পিছত AB−CD=11A−20D=24।
D=1,2,3 আৰু সুকীয়া অংক 1–6 ৰ সৈতে কেৱল A=4,D=1 কাম কৰে।
ক'ডটো হ'ল 4521 আৰু A×C+B×D=8+5=13।
