Question

the ratio of two numbers 3:4. if 7 is subtracted from each number, the ratio become 2:3. find the number​

Answer 1

Answer:

21 and 28

Step-by-step explanation:

let first no. be 3x

and second no. be 4x

according to question,

3x - 7/ 4x - 7 =2/3

(cross multiply)

3(3x-7) = 2(4x-7)

9x - 21 = 8x - 14

9x - 8x = - 14 + 21

x = 7

so,

first no. is 3 × 7 = 21

second no. is 4 × 7=28
