Step-by-step explanation:
let number of days the worker worked =x
and number of days he remained absent =y
given, x+y=40
=>y=40-x
it is also given, 250×x - 75×y = 8900
=> 250x - 75×(40-x) = 8900
=> 250x - 75×40 + 75x = 8900
=> 325x - 3000 = 8900
=> 325x = 8900 + 3000 = 11900
=> x = 11900/325 = 36.62
the days can not be a decimal no. I think some data is incorrect
