Aptitude Question – Discount (RRB NTPC)
Question:
The ratio of the sums of money Arun and Ahaan had is 9 : 5. If Arun gives ₹12 from his share to Ahaan, then the ratio will change to 4 : 3. How much money did Arun have initially?
Step-by-Step Solution
Ahaan = 5x
Arun = 9x
After giving ₹12:
Cross-multiplying:
3(9x − 12) = 4(5x + 12)
27x − 36 = 20x + 48
7x = 84 → x = 12
So Arun = 9x = 9 × 12 = ₹108.
Final Answer: ₹108.
