(D) Ram = Rs.1500, Shyam = Rs.1000, Mohan = Rs.752
(E) Ram = Rs.1500, Shyam = Rs.1000, Mohan = Rs.122
[CoT]: [1/2:1/3:1/4 = 6:4:3
Ram = 6/13 * 3250 = 1500

Question: The average of 13 numbers is 60. Average of the first 6 of them is 57 and that of the last 8 is 61. Find the 8th number?
Options:
(A) 46
(B) 48
(C) 50
(D) 52

[CoT]: [Sum of all the 13 numbers = 13 * 60 = 780
Sum of the first 6 of them = 6 * 57 = 342
Sum of the last 8 of them = 8 * 61 = 488
So, the 8th number = 342 + 488 - 780 = 50.]
