In First month Rs 100 deposited to warden. So after cut Rs 20 warden will have Rs 80. After got prize of Rs 50 for essay writing money deposit to warden = Rs 80 + Rs 50 = Rs 130 After consider number line – 

1. Mahesh spend in first month = Rs 120 (50 + 30 + 20 + 20) 

2. Rs 20, warden give him in the fourth week. 

3. Left side of zero. 

4. Rs 20 on the right side means +ve i.e., Mahesh’s money Rs 20 on the left side means ve i.ev warden’s money. 

5. Out of received money Rs 100 and Rs 50, Rs 20 on left side of zero and rest on right side of zero are marked. 

6. If Mahesh has to spend Rs 200 due to illness in second month then Mahesh will deduct Rs 70 to the warden and it denoted left side of the zero on number line.
