19 : 13 : 15
Incorrect Answer23 : 33 : 60
Correct Answer17 : 37 : 50
Incorrect Answer17 : 18 : 25
Incorrect AnswerExplanation:
Let's break down the scenario:
- Original salaries are in the ratio 2:3:5.
- Let's assume their salaries are 2x, 3x, and 5x.
Now, calculate the increased salaries:
- Father's salary increases by 15%: \(2x \times 1.15 = 2.3x\)
- Mother's salary increases by 10%: \(3x \times 1.10 = 3.3x\)
- Daughter's salary increases by 20%: \(5x \times 1.20 = 6x\)
New salary ratio:
\[2.3x : 3.3x : 6x\]
On simplifying (by dividing all by 0.1x), the ratio becomes:
\[23 : 33 : 60\]
That's option 2.
- Option 1: Not applicable; the numbers don't match.
- Option 3: No correlation with calculated values.
- Option 4: Discrepancy from calculated outcome.
Your option 2, 23 : 33 : 60, is correct.
