Working $5$ hours daily ,Shaheed can embroider sarees in $21$ days .How many days will it take for him to embroider 6 sarees working $7$ hours daily ?

Answer 1

Working $5$ hours daily, Shaheed can embroider $3$ sarees in 21 days.

no. of working hours for $3$ sarees $=21\times 5$

$=105$

So, no. of working hour for one saree$=105÷3$

$=35$ hours.

No. of working hours for $6$ sarees $=6\times 35$

$=210$ hours.

Given that in a day $7$ hours work is done.

So, no. of days required for $210$ hours $=210÷7$

$=30$ days.

So, $30$ days are required for embroider $6$ sarees working $7$ hour per day.
