1500, 1581, 1664, 1749, 1833, 1925, 2016

[Bank of Baroda (PO), 2008]


  • Explanation

    According to the question 

    ⇒ 1400+(10)²=1500

    ⇒ 1500+(9)²=1581

    ⇒ 1600+(8)²=1664

    ⇒ 1700+(7)²=1749

    ⇒ 1800+(6)²=1833(1836)

    ⇒ 1900+(5)²=1925

    ⇒ 2000+(4)²=2016

    ∴ Wrong number= 1833

    ∴ Right number = 1800+(6)2=1836. 

    Hence, Option C is correct.
