Question

Find out the missing number in the second figure on the basis of numbers arranged in the first figure

• A. 30
• B. 58
• C. 160
• D. 32

Answer 1

Answer: (B)

58

$(2^2+3^2+4^2)-(1^2+5^2)=(4+9+16)-(1+25)=3$
$(7^2+8^2+9^2)-({10}^2+6^2)=(49+64+81)-(100+36)$
$=58$
Hence, missing number = 58.
