FAQs Related To NCERT Solutions For Class 8 Maths Chapter 8
Here we have provided some of the frequently asked questions related to this chapter:
A: Let the money with Chameli be ₹100
Money spent by her = 75% of 100
= 75/100 × 100 = ₹75
The money left with her = ₹100 – ₹75 = ₹25
₹25 are left with her out of ₹100
₹1 is left with her out of ₹100/25
₹600 will be left out of ₹100/25 × 600 = ₹2400
Hence, she had ₹2400 in beginning.
(i) Speed of a cycle 15 km per hour to the speed of a scooter 30 km per hour
(ii) 5 m to 10 km
(iii) 50 paise to ₹5
A: i) Ratio of the speed of cycle to the scooter = 15/30 = 1:2
ii) Since 1 km = 1000m, so the required ratio is:
5m/10000m = 1:2000
iii) Since ₹1 = 100 paisa
₹5 = 500 paisa
So, the required ratio is 50 paise/500 paise = 1/10 = 1:10
(i) 3:4
(ii) 2:3
A: i) 3:4 = 3/4 = 3/4 x 100/100 = 3/4 x 100% = 75%
ii) 2:3 = 2/3 = 2/3 x 100/100 = 2/3 x 100% = 66.6%
A: It is given that 72% of 25 students are good in mathematics.
Therefore,
Percentage of students who are not good in mathematics = (100 − 72)%
= 28%
∴Number of students who are not good in mathematics = 28/7 x 100
= 7
Thus, 7 students are not good in mathematics.
A: Percentage of people who like other games = (100 − 60 − 30)%
= (100 − 90)% = 10 %
Total number of people = 50 lakh
Therefore, the number of people who like cricket = (60/100 x 50) = 30 lakh
Number of people who like football = (30/100 x 50) = 15 lakh
Number of people who like other games = (10/100 x 50) = 5 lakh
