Detailed Solution

Since Sarita saves Rs.20 every day, by the end of day 4, she has Rs.190+Rs.20=Rs.210

Since Rahul saves Rs.30 every day, by the end of day 3, he has Rs.120+Rs.30=Rs.150

By the end of day 4, he has Rs.150+Rs.30=Rs.180

 Day 1Day 2Day 3Day 4Day 5Day 6
Sarita150170190210  
Rahul90120150180  

Total savings by end of Day 4 = Rs.210 + Rs.180 

                                            = Rs.390
