Question

Spiderman crawls 12 m up and falls back 5 m every alternate hour.if the building is 63 m high, how long will it take spiderman to reach the top.

Answer 1

so first 1hour he climbs up 7 m
second hour he climbs 12 m and doesn't fall back right?

Answer 2

well its kind of confusing

Answer 3

yea it is
maybe he climbs 12 m first hour then 7 m the second!

Answer 4

u may assume as u think is right.

Answer 5

ok
then sequence is 7 + 12 + 7 + 12 + 7 + 12
that's 57 m in 6 hours
so he has 6 m to go
he can climb this in 0.5 hours
so i guess that is 6.5 hours

Answer 6

if we take the other scenario
12+7+12+7+12+ 7
= 57
its the same right?

Answer 7

lest me give u options

a.) 18 hrs b.) 17 hrs c.) 16 hrs 30 min d.) 16 hrs 40 minutes

Answer 8

ur "procedure" is correct

Answer 9

maybe he doesn't do the last 6 meters in one go - I dont know to be honest and I have to go

Answer 10

ok , i think it just depends on the interpretation of the question.

Answer 11

18 hrs ?

Answer 12

no, haha

Answer 13

it better be 17 hrs then

Answer 14

nono

Answer 15

lol are u trying every option

Answer 16

12*9 -5*8 = 68

this gives me 9 ups (9 hours) and 8 downs (8 hours)

9 + 8 = 17 hrs

Answer 17

look at the question its 63 not 68

Answer 18

12*8 - 5*8 = 56 is too short

Answer 19

well i gtg now , this is a nice little tricky question.

Answer 20

it maybe a nice question, but the question has to be phrased unambiguously

Answer 21

yes but options make it clearer i think.

Answer 22

it could be anything based on how we interpret the problem

Answer 23

i gave you justification for 17hrs earlier

Answer 24

if the minimum time interval is assumed to be 5 minutes, we get 16hrs 35 mnts which is not even there in options :/

Answer 25

yes but 12*9 -5*8 = \(68\) but the building is \(63\) m high.

Answer 26

17hrs is right if we assume the minimum time interval is 1 hour

Answer 27

lol actually 16 hrs and 35 min is correct haha

Answer 28

the question doesn't clearly specify whether the spiderman crawls continuously or he leaps 12 m every one hour.

Answer 29

thats what makes this question tricky

Answer 30

Nope. tricky questions are fun, poorly phrased questions are not :P

Answer 31

otherwise it would be no fun. i also failed first time

Answer 32

it may be poorly phrased but it is funny.
