Question

Q4. The lengths of three pieces of cardboard are in the ratio 8 : 10:15. If the length of the
longest piece of cardboard is 4.5 cm, find the difference in the lengths of other two pieces of
cardboard.

Answer 1

Answer:

Let's take the ratio be X.

1st length= 8x

2nd=10x

3rd=15x

A/Q,

15x= 4.5 ( it is the longest length)

X= 4.5/15

X= 0.3

1st length= 8x

8x0.3 =2.4 cm

2nd length= 10x0.3= 3 cm

Difference = 3-2.4 =0.6 cm
