@sauravd2001
from his options , i think they are not overlapping .
2 hands are at diff.positions but equidistant

@maddy2807 & others sorry for confusion by equidistant i mean 8 no is in between the hour and minute hand.. otherwise sir u r right!!
@rubikmath haanji sir not overlaping..
@pratyush9811

ek aur clock ka question??

@pratyush9811 throw in. will try
@pratyush9811 dekh ghadi banale ek
ab dekh 30 min ka jab fasla woh tay kar leti hai toh 7aur 8 ke bilkul bich mein aa jati hai ghante wala hath aur ab dekh iska matlab har 2.4 mein 1 step age leti hai(jise 1 min. kahte hin use step man liya ) thi k hai is tarah se 3.5 pe hoga 42 minutes ..ab dekh
iska matlba hua 2 aur 1.5 ka difference not possible and options tere bahut loose hin toh dekh ab age badha nai skate kyunki difference badega toh bacha kam wala hi 41.53 hi ayega
A man goes out between 5 to 6 P.M. , when he comes back between 6 to 7 P.M. he observes that 2 hands of the clock interchanged their position, the time when he went out was??

41.53

point me if wronf
approach 6t =240+x
210+ 1/2 t =240-x
t=41.53
@sauravd2001 iska better approach and trick hai mere pass.. it has asked for 7-8 next digit is 9, multiply it with 5=45 and multiply it to 12/13.. for e.g if it has asked for 5-6 then 7*5*12/13=answer
@rubikmath doesnt this question have problem he says 5 se 6 ke bich mein bahar kabhi bhii bahar man le gaya hoga 5:30 gaya
ab woh wapas aya 6:27.5 pe toh answere aa gaya iski range ni ayegi ?? :P
