दो संख्याएँ 1 : 2 के अनुपात में हैं, जब प्रत्येक में 4 जोड़ा जाता है,तो अनुपात 2 : 3 होगा। संख्याएँ क्या होगी?


lalitgumber10: firstly 1:2 means if 1st no. is X then 2nd no. is 2X after add 4 in both no. (X + 4)/(2X + 4) = 2/3. 3(X + 4) = 2(2X + 4) => 3X + 12 = 4X + 8. => 3X + 12 -8 = 4X. => 12 - 8 = 4X - 3X. => 4 = X. So, X = 4 then the two no.'s is 4 and 8

Two numbers are in the ratio 1 : 2

Let the common multiple be x

So, let the first number be x and 2nd be 2x

After adding 4 to bith the numbers, the numbers becomes:

1st number = x + 4

2nd number = 2x + 4


According to the given condition,

\dfrac{x + 4}{2x + 4}\:=\: \dfrac{2}{3}

3(x\:+\:4)\:=\:2(2x\:+\:4)

3x\:+\:12\:=\:4x\:+\:8

12\:-\:8\:=\:4x\:-\:3x

4\:=\:x

x\:=\:4


∴ 1st number ➾ x

\underline{\underline{\tt{4}}}


∴ 2nd number ➾ 2x

➾ 2 × 4

\underline{\underline{\tt{8}}}

माना कि वो दो संख्याएँ क्रमश: x और 2x है।


प्रश्न के अनुसार,

 =  >  \frac{x + 4}{2x + 4}  =  \frac{2}{3} \\  \\  =  >  3(x + 4) = 2(2x + 4) \\  \\  =  > 3x + 12 = 4x + 8 \\  \\  =  > 3x - 4x = 8 - 12 \\  \\  =  >  - x =  - 4 \\  \\  =  > x = 4


इसलिये,
एक संख्या = x = 4
और दूसरी संख्या = 2x = 2 × 4 = 8
