Difficulty: Medium
Correct Answer: None of these
Explanation:
Introduction:
(Reserved duplicate to ensure clarity that the computed total is not among the numerical choices.) This mirrors the earlier hotel bill structure and reinforces solving with an unknown overall average A.
Given Data / Assumptions:
13 spend Rs 79 each; 6 spend A + 4 each. Total = 19A.
Concept / Approach:
Set 13*79 + 6*(A+4) = 19A and solve for A, then compute 19A.
Step-by-Step Solution:
1051 + 6A = 19A ⇒ 13A = 1051 ⇒ A ≈ 80.8461538. Total ≈ 19 * 80.8461538 ≈ Rs 1,536.08.
Final Answer:
Since Rs 1,536.08 is not listed numerically among options a–d, the correct choice remains None of these.
