Linked price ratio with difference: The prices of a scooter and a television are in the ratio 8 : 7. A scooter costs ₹ 2000 more than a television. Find the price of the television.

Difficulty: Easy

Correct Answer: ₹ 14000

Explanation:


Introduction / Context:
When two prices are in a ratio and their difference is given, you can treat each price as a multiple of a common unit value. The difference equals the difference of ratio parts multiplied by that unit value.


Given Data / Assumptions:

  • Scooter : Television = 8 : 7.
  • Scooter − Television = ₹ 2000.


Concept / Approach:
Let Scooter = 8k and Television = 7k. Then (8k − 7k) = k = 2000. Hence Television = 7k = 7 × 2000.


Step-by-Step Solution:
k = ₹ 2000.Television price = 7k = ₹ 14,000.


Verification / Alternative check:
Compute scooter price: 8k = ₹ 16,000; difference is ₹ 2000 and ratio 16000 : 14000 reduces to 8 : 7, confirming the setup.


Why Other Options Are Wrong:

  • ₹ 10000 and ₹ 18000 don’t maintain an 8 : 7 ratio with a ₹ 2000 gap.
  • ₹ 28000 doubles the correct television price.


Common Pitfalls:

  • Forgetting that the difference corresponds to exactly one ratio part (8 − 7 = 1).


Final Answer:
₹ 14000
