Answer:
Share of Sinu is Rs. 15.
Step-by-step explanation:
Given:
Number of days taken by Sita and Sinu to finish a work = 50
Number of days taken by Sita , Sinu and Smitha to finish a work = 6
Amount earn by completing the work = Rs. 250
To find: Share of Sinu is Sita takes 100 days alone.
Work done by both Sita and Sinu in a day = 1/50
Work done by both Sita , Sinu and Smitha in a day = 1/6
Work done by Sita in a day = 1/100
⇒ Work done by Sinu in a day = 1/50 - 1/100 = 1/100
Let everyone get there share according to the work they done.
So, Share of Sinu = (1/100)/(1/6) × 250 = 6/100 × 250 = Rs. 15
Therefore, Share of Sinu is Rs. 15
