Question

a pole of height 3metres is struck by a speeding car and breaks into two pieces such that the first piece is1/2 of the second. find the lenght of both pieces ( do in copy ans send image)​

Answer 1

Answer:

A pole of height 3 metres is struck by a speeding car and breaks into two piece such that the first piece is 21

Total height of pole =3 metres

Let length of 2nd piece =x

Length of 1st piece = 21 x

Ratio of length of two parts = 21

x:1x= 21 : 11

Taking L.C.M. of 2 and 1

=( 21 ×2) :( 11×2)

=1:2

Sum of terms of ratio =1+2=3

∴ Length of 1st part = 31 of 3 m

=( 31 ×3)m=1 m

Length of 2nd part = 31 of 3 m

=( 32 ×3)m=2 m

Length of 1st part =1 m

Length of 2nd part =2 m
