Explanation:

Let the common ratio of the given ratios be x.

Therefore, the required numbers will be x, 2x, 3x and 4x.

According to the given information:

x + 2x + 3x + 4x = 16

10 x = 16

x =  \frac{16}{10}  \implies x =  \frac{8}{5}  \\ 2x = 2 \times  \frac{16}{10}  \implies x =  \frac{16}{5}  \\ 3x = 3 \times  \frac{16}{10}  \implies x =  \frac{24}{5}  \\ 4x = 4 \times  \frac{16}{10}  \implies x =  \frac{32}{5}  \\ sum \: of \: first \: and \: fourth \: no.  \\ =  \frac{8}{5}  +  \frac{32}{5}  =  \frac{8 + 32}{5}  =  \frac{40}{5}  = 8

अज्ञात संख्या को x होने दें

इसलिए आवश्यक संख्याएं हैं =x,2x,3x,4x

अब, सवाल के अनुसार

x+2x+3x+4x=16

⟹10x= 16

 \bold{⟹x =  \frac{16}{10} }

 \bold{⟹x =  \frac{8}{5} }

फिर

 \bold{x =  \frac{8}{5} }

 \bold{2x =  \frac{8}{5}  \times 2 =  \frac{16}{5} }

 \bold{3x =  \frac{8}{5}  \times 3 =  \frac{27}{5} }

 \bold{4x =  \frac{8}{5}  \times 4 =  \frac{32}{5} }

प्रथम और चतुर्थ का योग =  \bold{ \frac{8}{5}  +  \frac{32}{5}  =  \frac{40}{5}  = 8}
