Are the following statements true? (a) 40 persons : 200 persons = ₹ 15 : ₹ 75 (b) 7.5 litres : 15 litres = 5 kg : 10 kg (c) 99 kg : 45 kg = ₹ 44 : ₹ 20 (d) 32 m : 64 m = 6 sec : 12 sec (e) 45 km : 60 km = 12 hours : 15 hours

(a)40 persons : 200 persons = ₹ 15 : ₹ 75

On taking the ratios we get

40 / 200 = 1 / 5

15 / 75 = 1 / 5

Therefore, the given set of ratios are True

(b) 7.5 litres : 15 litres = 5 kg : 10 kg

On taking the ratios we get

7.5 / 15 = 1 / 2

5 / 10 = 1 / 2

Therefore, the given set of ratios are True

(c) 99 kg : 45 kg = ₹ 44 : ₹ 20

On taking the ratios we get

99 / 45 = 11 / 5

44 / 20 = 11 / 5

Therefore, the given set of ratios are True

(d) 32 m : 64 m = 6 sec : 12 sec

On taking the ratios we get

32 / 64 = 1 / 2

6 / 12 = 1 / 2

Therefore, the given set of ratios are True

(e) 45 km : 60 km = 12 hours : 15 hours

On taking the ratios we get

45 / 60 = 3 / 4

12 / 15 = 4 / 5

Therefore, the given set of ratios are False
