\huge{\underline{\pink{\tt{Given,}}}}

  • The Three Number of Average is 44.
  • The Second Number is twice the First and also thrice the third Number .

\huge{\underline{\pink{\tt{To \ Find,}}}}

  • The Smallest Number

\huge{\underline{\pink{\tt{Solution :}}}}

\implies Suppose the First Number be \red{\sf{a}}

So, Second Number will be \red{\sf{2b}}

And, Third Number will be \red{\sf{2a/3 }}

\star{\underline{\sf{\purple{According\:to\:the\:given\:Condition:}}}}

  • The average of the three numbers is 44, therefore the sum of these three numbers would be \boxed{\sf{44 \times 3 = 132}}.

Now, According to the Question :

  • The Average of the three Number is 44

\longrightarrow \red{\tt{\dfrac{\:Sum\:of\:All\:Observation}{Number\:of\:Observation }}}

\longrightarrow \sf{\dfrac{\dfrac{a + 2a + 2a}{3}}{3}= 132}

\longrightarrow \sf{\dfrac{3a + 6a + 2a}{3} = 132}

\longrightarrow \sf{\dfrac{11a}{3} = 132}

\longrightarrow \sf{11a = 396}

\longrightarrow \sf{a = \dfrac{396}{11}}

\longrightarrow \boxed{\tt{a = 36}}

Therefore, The Numbers are :

  • \red{\sf{First\:Number}} (a) = 36
  • \red{\sf{Second\:Number}} (2a)= 36 ×2 = 72
  • \red{\sf{Third\:Number}} (2a/3)= 72/3 = 24

\boxed{\sf{\pink{Smallest\:Number = Third\:Number = 24}}}}

\rule{200}2
