**CBSE NCERT Solutions for Class 8 Maths Chapter 8:**

*Question-1*:

Find the ratio of the following.

(a) Speed of a cycle 15 km per hour to the speed of scooter 30 km per hour.

(b) 5 m to 10 km

(c) 50 paise to Rs 5

*Solution*:

a) Required ratio =15/30 = 1/2 = 1: 2

b) Required ratio = 5m/10 km

= 5 m/ (10 *1000 m)

= 5 / (10 *1000 )
=(5/10) * (1/1000)
=(1/2) * (1/1000)
= (1/ 2* 1000)

= 1/2000

= 1: 2000

c) Required ratio = 50 paise/Rs 5

= 50paise/500 paise

= 1/10 = 1:10

*Question-2*:

A football team won 10 matches out of the total number of matches they played. If their win percentage was 40, then how many matches did they play in all?

*Solution*:

Let us assume total number of matches = y

Then % of matches win= (10/y) * 100

Now , it is given % of matches win=40

So,

40=(10/y)* 100

y=(10/40) *100 =25

*Question-3*:

If Chameli had Rs 600 left after spending 75% of her money, how much did she have in the beginning?

*Solution*:

Money left after spending 75% = 100-75 = 25%

Let us assume total money in the beginning = y

Then, 25% of y =600

(25/100) * y =600

y = (100/25) *600

y = 2400

Chameli had Rs. 2,400 in the beginning.
