Read Solution (Total 17)
-
- Total amount=60 cm long .
He gives Raja 1/2 of it i.e=1/2*60=30 cm long.
left with Hari now=60-30=30
Again he gives Gopal 1/4th of what is left i.e=1/4*30=7.5
NOw left=30-7.5=22.5
Now let he gave Sahil=x,
Then A2q, 22.5-x=1/10*60
After solving this we get x=16.5 cm which is required.
So option B will be correct.

- Total amount=60cm
then after giving to raja he has left =30cm
then he gives Gopal 1/4of 30cm=7.5cm
left=30-7.5=22.5cm
now let he gives to sahil x cm..
so equation is---->
22.5-x=60*1/6
x=16.5 - 8 years agoHelpfull: Yes(2) No(1)
- let hari has 60.by giving half(30) to raja,he has 30.by giving 30/4 to gopal,hari is left with(30-30/4)=90/4.90/4-x=60/10, where x is of sahil, x=33/2=16.5

- 16.5
1/2+1/8+1/8+X=1 ==>x=11/40==>16.5cm - 8 years agoHelpfull: Yes(0) No(0)
- Total amount=60 cm long .
He gives Raja 1/2 of it i.e=1/2*60=30 cm long.
left with Hari now=60-30=30

NOw left=30-7.5=22.5
After giving a piece to Sahi, be is left with 1/10th of the original
so 60*(1/10)=6
since, 22.5-6=16.5

- H=60 cm
he gives raja half of 60 cm i.e=30 cm
and left ammount is 30 cm
again he gives 1/4 part to gopal i.e=7.5
and remaining part =22.5
and condition is remaining part - sahi's part=1/10 of original
ie.=> 22.5-x=1/10(60)
=22.5-6=x
=>x=16.5cm
so sahi get 16.5cm - 8 years agoHelpfull: Yes(0) No(0)

NOw left=30-7.5=22.5
Now let he gave Sahil=x,
Then A2q, 22.5-x=1/10*60
After solving this we get x=16.5 cm which is required.
