DIRECTIONS for the question: Solve the following question and mark the best possible option.
A man is paid Rs. 30 per day for each day he works and forfeits Rs. 10 each day he is absent. At the end of 25 days he got Rs. 550. Find the number of days he worked?
A)
22 days
B)
18 days
C)
25 days
D)
20 days
E)
15 days
D
Let he works for x days and is absent for y days. So x + y = 25…….(i)
And 30x – 10y = 550……(ii) Solving these equations we get x = 20.
