Answer:
65 days
Step-by-step explanation:
The numberof boys doing a assignment and the number of days taken are in inverse proportion.
Let the number of days taken by 28 boys be a
Then, 35:a:: inverse ratio of 52:28
=>35:a=28:52
Applying the rule, product of extremes = product of means
35×52=a×28
a= 35×52/28
a=65
Hence, 28 boys can do the assignment in 65 days
