Let’s solve each question step by step.
---
Question 1:
Isha’s weight = 25 kg
Father’s weight = 75 kg
Ratio of Isha’s weight to father’s weight = 25 : 75
Simplify by dividing both by 25 → 1 : 3
✔ Correct answer:
a. 1:3
---
Question 2:
Lizard length = 20 cm
Crocodile length = 4 m → convert to cm: 4 × 100 = 400 cm
Ratio = 20 : 400
Divide both by 20 → 1 : 20
✔ Correct answer:
b. 1:20
---
Question 3:
Length = 50 m, Breadth = 15 m
Ratio of length to breadth = 50 : 15
Divide both by 5 → 10 : 3
✔ Correct answer:
c. 10:3
---
Question 4:
Total persons = 45
Females = 25 → Males = 45 - 25 = 20
Ratio of females to males = 25 : 20
Divide both by 5 → 5 : 4
✔ Correct answer:
d. 5:4
---
Question 5:
Investment ratio Ravi : Rani = 2 : 3
Total parts = 2 + 3 = 5
Total profit = Rs 40,000
Ravi’s share = (2/5) × 40,000 = 16,000
✔ Correct answer:
a. Rs 16000
---
Question 6:
If two ratios are equal, we say they are in
proportion.
✔ Fill in:
proportion
---
Question 7:
In a proportion like a : b :: c : d, the first and fourth terms (a and d) are called
extremes.
✔ Fill in:
extremes
---
Question 8:
Ratio of Maria’s distance : Karan’s distance = 1 : 2
That means Maria’s distance is smaller → she lives nearer.
✔ Answer:
Maria lives nearer to the school.
---
Question 9:
Divide Rs 60 in ratio 1 : 2 between Kirti and Kamal.
Total parts = 1 + 2 = 3
Kirti gets (1/3) × 60 = Rs 20
Kamal gets (2/3) × 60 = Rs 40
✔ Answer:
Kirti gets Rs 20, Kamal gets Rs 40
---
Final Answer:
1. a. 1:3
2. b. 1:20
3. c. 10:3
4. d. 5:4
5. a. Rs 16000
6. proportion
