Verified Answer
There are three pillars X, Y and Z of different heights. Three spiders...
A = 39 × 5 + 1 × 6 = 201
B = 39 × 4 + 1 × 7 = 163
C = 39 × 4.5 + 1 × 6.5 = 182
Hence, the correct option is (b).
B = 39 × 4 + 1 × 7 = 163
C = 39 × 4.5 + 1 × 6.5 = 182
Hence, the correct option is (b).

There are three pillars X, Y and Z of different heights. Three spiders...
Solution:
Given, A climbs X by 6 cm but slips down 1 cm. So, in one chance A climbs (6-1)=5 cm.
Similarly, B climbs Y by 7 cm but slips down 3 cm. So, in one chance B climbs (7-3)=4 cm.
C climbs Z by 6.5 cm but slips down 2 cm. So, in one chance C climbs (6.5-2)=4.5 cm.
It is given that each of them requires 40 chances to reach the top of the pillars.
So, the height of pillar X can be calculated as follows:
Height of pillar X = 40 × 5 = 200 cm
Similarly, the height of pillar Y = 40 × 4 = 160 cm
and the height of pillar Z = 40 × 4.5 = 180 cm
Therefore, the shortest pillar is Y with a height of 160 cm.
Hence, the correct option is (B) 163 cm.
Given, A climbs X by 6 cm but slips down 1 cm. So, in one chance A climbs (6-1)=5 cm.
Similarly, B climbs Y by 7 cm but slips down 3 cm. So, in one chance B climbs (7-3)=4 cm.
C climbs Z by 6.5 cm but slips down 2 cm. So, in one chance C climbs (6.5-2)=4.5 cm.
It is given that each of them requires 40 chances to reach the top of the pillars.
So, the height of pillar X can be calculated as follows:
Height of pillar X = 40 × 5 = 200 cm
Similarly, the height of pillar Y = 40 × 4 = 160 cm
and the height of pillar Z = 40 × 4.5 = 180 cm
Therefore, the shortest pillar is Y with a height of 160 cm.
Hence, the correct option is (B) 163 cm.
