Ratio of two numbers is 3:4. If 6 is added to each, the new ratio is 4:5. The numbers are
A12 and 16
B18 and 24
C24 and 32
D30 and 40
Answer & Solution
Correct answer: B. 18 and 24
Numbers: 3k, 4k. (3k+6)/(4k+6) = 4/5. Cross-multiply: 15k + 30 = 16k + 24, so k = 6. Numbers are 18 and 24. Check: (18+6)/(24+6) = 24/30 = 4/5 ✓.
