    Question

    If the sum of squares of two positive numbers is 2437 and square root of one number is 7, find the other number.

    A.

    6

    B.

    16

    C.

    12

    D.

    8

    Correct option is A

    Given:

    The sum of the squares of two numbers is 2437.

    The square root of one number is 7, i.e., the number is 72=497^2 = 49​​

    Concept Used:

    If two numbers are a and b, and their squares sum to a given value, then:

    a2+b2=Given Suma^2 + b^2 = \text{Given Sum}​​

    We can rearrange to solve for b.

    Solution:

    a2+b2=2437a^2 + b^2 = 2437​​

    Substitutinga2=492=2401 a^2 = 49^2 = 2401​​

    b2=24372401b^2 = 2437 – 2401​​

    b2=36b^2 = 36​​

    b=6

    Option (a) is right.
