Number of saplings planted = 500000 ÷ 250 = 2000

Number of saplings Saravanan has = 2560

Number of saplings planted = 2000

**Number of saplings left = 560**

A squirrel wants to eat the grains quickly. Help the Squirrel to find the shortest
way to reach the grains. ( Use your scale to measure length of the line segments)**

AB + BC + CD + DE

(1.7 + 2.2 + 2 + 1.7) cm = **7.6 cm**

AG + GF + FE

(2.2 + 1.5 + 1.5 + 2.3) cm = **7.5 cm**

AH + HI + IJ + JE

(2.5 + 2 + 0.7 + 2.7) cm = **7.9 cm**

**The shortest way to reach the grains is the way from A through
G, F and reach E.**

**8. A post office functions from 10 a.m to 5.45 p.m
with a lunch break of 1 hour. If the post office works for 6 days a week, find the

The duration of working hours in one day

**Working hours in 1 day = 6.45 hrs**

Working hours in 6 days = 6.45 × 6

= 36 hrs 270 mts.

= 36 hrs + 4 hrs 30 minutes

= 40 hrs 30 minutes

**Total duration of working hours in a
week = 40 hours 30 minutes.**

Seetha wakes up at 5.20 am = 5 hours 20 minutes

Time taken to get ready = 35 minutes

Traveling Time = 15 minutes

The time she reached the railway station = 5
hours 70 minutes

= 5hrs + (60 +10) minutes

= 6 hours 10 minutes

**The train departure time** **=
6 hours **

**So, Seetha will not catch the train**
