C Correct answer
Explanation

A:P = 8:5. P = (10/13)M, so M = 1.3P. Total = A + P + M = 1.6P + P + 1.3P = 3.9P = 273. P = 70. A = (8/5)*70 = 112. Difference = 112 - 70 = 42.

AI explanation

The ratio of Mahesh's amount to Pravin's amount is 13 : 10. We know Arvind to Pravin is 8 : 5, which can be scaled to 16 : 10 to match Pravin's parts. The total parts are 16 (Arvind) + 13 (Mahesh) + 10 (Pravin) = 39 parts. With the total amount being Rs. 273, one part equals 273 / 39 = Rs. 7. The difference between Arvind and Pravin is 16 parts minus 10 parts = 6 parts, so Arvind has 6 * 7 = Rs. 42 more. Arvind has Rs. 42 more than Pravin.
