If two numbers are in the ratio 2:3.
If two numbers are in the ratio 2:3. If 15 is added to both of the numbers then the ratio becomes 3:4 then find the smallest number?
Answer/Solution
D)30
Steps/Work
2:3
2x + 15 : 3x + 15 = 3 : 4
4[2x + 15] = 3[3x + 15]
8x + 60 = 9x + 45
9x - 8x = 60 - 45
x = 15
Then smallest number is = 2
2x = 30
Correct Option D
2x + 15 : 3x + 15 = 3 : 4
4[2x + 15] = 3[3x + 15]
8x + 60 = 9x + 45
9x - 8x = 60 - 45
x = 15
Then smallest number is = 2
2x = 30
Correct Option D
