Question

16. There are three pillars x, y and z of different heights. Three spiders a, b and c start to climb on these pillars simultaneously. In one chance, a climbs on x by 6 cm but slips down 1 cm. B climbs on y by 7 cm but slips down 3 cm. C climbs on z by 6.5 cm but slips down 2 cm. If each of them requires 40 chances to reach the top of the pillars, what is the height of the shortest pillar?

Answer 1

Answer:

160cm

Step-by-step explanation:

In a chance spider A climbs 6-1 =5cm

In 40 chances it climbs 40(5)cm =200cm

Similarly spider b climbs 40 (4)cm =160cm

spider c climbs( 6.5 - 2)cm = 4.5(40)cm =180 cm
