Question

An employer pays Rs. 30 for each day a worker work, and deducts Rs. 5 for
each day he is idle. At the end of 50 days, a worker gets Rs.450. For how many
days did the worker remain idle?
​

Answer 1

Answer:

30 days he was idle

Step-by-step explanation:

Let the days the worker worked be x

So the days he was idle = 50 - x

So at the end of 50 days the worker will get money

= x×30 - [ ( 50-x) × 5 ]

= 30x - 250 + 5x

= 35 x -250 = 450

35x = 450 + 250

= 700

x = 700 ÷ 35

= 20 days he worked for

The worker remained idle for

=50 - 20

= 30 days he was idle
