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,
∴
∴
∴
∴
∴
∴ 1st number ➾ x
➾
∴ 2nd number ➾ 2x
➾ 2 × 4
➾
