Question

If 83 : 45 :: 72 : ? solve and find the answer​

Answer 1

Answer: $x=\dfrac{3240}{83}$

Step-by-step explanation:

Given: 83 : 45 :: 72 : ?

Let unknown quantity (?) be x.

Now, x : y :: a : b

$\Rightarrow\ \dfrac{x}{y}=\dfrac{a}{b}$

83 : 45 :: 72 : x

$\Rightarrow\ \dfrac{83}{45}=\dfrac{72}{x}\\\\\Rightarrow\ x=\dfrac{72}{83}\times45\\\\\Rightarrow\ x=\dfrac{3240}{83}$

Hence, $x=\dfrac{3240}{83}$
