Find below the list of all AP Board Class 7th Maths Chapter 6 Ratio Applications Ex 3 Textbook Solutions for PDF’s for you to download and prepare for the upcoming exams:Question 1.
A length of a bacteria enlarged 50,000 times attains a length of 5 cm. What is the actual length of the bacteria? If the length is enlarged 20,000 times only, what would be its enlarged length?
Solution:
After enlarging 50,000 times the length is 5 cm.
Without enlarging (1 – times) the length Is x cm say
∴ 50,000 : 5 :: 1 : x
By rule of properties
50,000 × x = 5 × 1
x = 550,000=110,000 = 0.0001 cm
Question 2.
Observe the following tables and fmd if x is directly proportional.
Solution:
(i)
In all the cases 𝑥𝑦 is constant.
∴ x ∝ y (x is directly proportional toy)
(ii)
Here the change/increase is not uniform.
(i.e.,) 𝑥𝑦 is not same in all cases.
∴ x is not directly proportional to y.
(iii)
Here the change/increase is not uniform.
(i.e.,) 𝑥𝑦 is not same in all cases.
∴ x is not directly proportional to y.
Question 3.
Sushma has a road map with a scale of 1 cm representing 18 km. She drives on a road for 72 km. What would be her distance covered in the map?

18x = 72 × 1
x = 7218 = 4cm
