Nineteen friends go to a restaurant for dinner. Thirteen of them spend Rs 79 each, and each of the remaining six spends Rs 4 more than the overall average expenditure of all nineteen. What is the total amount spent by the group?

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.
