Question

during environment week, school children planted 141 saplings. on Monday 23 saplings were planted, on Tuesday 31, on Wednesday 33, on Thursday 25 and rest on Friday. how many were planted on Friday?​

Answer 1

Answer:

total no. of saplings=141

saplings planted on Monday +Tuesday+Wednesday+thursday

=23+31+33+25

=112

so,

total - favourable

141-112

29

therefore 29 saplings are planted on Friday

Answer 2

Total saplings planted = 141

Let the number of saplings planted on Friday be = x

Number of saplings planted on Monday = 23

Number of saplings planted on Tuesday = 31

Number of saplings planted on Wednesday = 33

Number of saplings planted on Thursday = 25

23 + 31 + 33 + 25 + x = 141

112 + x = 141

x = 141 - 112

x = 29

Number of saplings planted on Friday = 29
