10. If 8kg of wheat costs 320 rupees, what will be the cost of 20kg of wheat?

ANSWERS:

1. Number of boys = 15
   Total number of students = 30
   Required ratio = 15: 30 = 1:2 (Divide by the common factor 15)
2. 1 rupee = 100 paise
   2 rupees = 200 paise
   Required ratio = 50: 200 = 1:4 (Divide by the common factor 50)
3. 1kg = 1000 g
   Required ratio = 250: 1000 = 1:4 (Divide by the common factor 250)
4. 1 hour = 60 minutes
   2 hours = 120 minutes
   Required ratio = 40:120 = 1:3 (Divide by the common factor 40)
5. 2 weeks = 14 days
   Required ratio = 14:4 = 7:2 (Divide by the common factor 2)
6. Total number of persons = 48
   Number of men = 36
   Number of women = 12
   Required ratio = 36:12 = 3:1 (Divide by the common factor 12)
7. The given ratio = 4:6 = 2:3 (Divide by the common factor 2)
   4:6 = 8:12 (Multiply both numerator and denominator by 2)
8. 16:24 = 2:3 (Divide by the common factor 8)
   10:15 = 2:3 (Divide by the common factor 5)
9. Price of 5m of cloth = 495 rupees
   Price of 1m of cloth = 99 rupees
   Price of 12m of cloth = 99 x 12 = 1188 rupees
10. Cost of 8kg wheat = 320 rupees
    Cost of 1 kg wheat = 320/8 = 40 rupees
    Cost of 20kg of wheat = 20 x 40 = 800 rupees
