• ₹ 90

• ₹ 89 

Answer 1

₹ 90
Explanation:
Here, Reema, Ruchi, and Richa can make a painting in 15, 20 and 30 days, respectively

So, the efficiency of Reema, Ruchi and Richa = 4 : 3:  2

∴ Share of Reema =`810/9xx4=360`

Share of Ruchi =`810/9xx3=270`

∴ The share of Reema exceeds that of Ruchi by
= (360 − 270)= ₹ 90
