Answers
Answer:
Compare the income of A, B, C and D.
A = 54 * B or B = 45 * A
C = 54 * A
A = 65 * D or D = 56 * A
E = 65 * A
In order for the amounts earned by A, B, C, D and E to be integers, the amount earned by A should be a multiple of 4, 5 and 6. Or, the amount earned by A should be a multiple of 60. The only multiple of 60 that is a 2–digit number is 60.
So, if A earns Rs. 60, B should earn Rs. 48. C should earn Rs. 75, D should earn Rs. 50 and E should earn Rs. 72.
The total income earned by all 5 of them should be equal to
Rs. 60 + Rs. 48 + Rs. 75 + Rs. 50 + Rs. 72 => Rs. 305
The question is " What is the total amount earned by all five of them put together?"
The total income earned by all 5 of them should be equal to Rs. 305
Hence, the answer is Rs. 305
