Answers
Answer:
Statement (a) is TRUE.
Statement (b) is TRUE.
Statement (c) is TRUE.
Statement (d) is TRUE.
Statement (e) is NOT TRUE.
Step-by-step explanation:
(a) 40 persons : 200 persons = 40 : 200 = 1 : 5
Rs15 : Rs 75 = 15 : 75 = 1 : 5
Therefore, Statement (a) is TRUE.
(b) 7.5 litre : 15 litres = 7.5 : 15 = 75 : 150 = 1 : 2
5 kg : 10 kg = 5 : 10 = 1 : 2
Therefore, Statement (b) is TRUE.
(c) 99 kg : 45 kg = 99 : 45 = 11 : 5
Rs 44 : Rs 20 = 44 : 20 = 11 : 5
Therefore, Statement (c) is TRUE.
(d) 32 m : 64 m = 32 : 64 = 1 : 2
6 sec : 12 sec = 6 : 12 = 1 : 2
Therefore, Statement (d) is TRUE.
(e) 45 km : 60 km = 45 : 60 = 3 : 4
12 hours : 15 hours = 12 : 15 = 4 : 5
Therefore, Statement (e) is NOT TRUE.
Answer:
Statement (a) is TRUE.
Statement (b) is TRUE.
Statement (c) is TRUE.
Statement (d) is TRUE.
Statement (e) is NOT TRUE.
Step-by-step explanation:
(a) 40 persons : 200 persons = 40 : 200 = 1 : 5
Rs15 : Rs 75 = 15 : 75 = 1 : 5
Therefore, Statement (a) is TRUE.
(b) 7.5 litre : 15 litres = 7.5 : 15 = 75 : 150 = 1 : 2
5 kg : 10 kg = 5 : 10 = 1 : 2
Therefore, Statement (b) is TRUE.
(c) 99 kg : 45 kg = 99 : 45 = 11 : 5
Rs 44 : Rs 20 = 44 : 20 = 11 : 5
Therefore, Statement (c) is TRUE.
(d) 32 m : 64 m = 32 : 64 = 1 : 2
6 sec : 12 sec = 6 : 12 = 1 : 2
Therefore, Statement (d) is TRUE.
(e) 45 km : 60 km = 45 : 60 = 3 : 4
12 hours : 15 hours = 12 : 15 = 4 : 5
Therefore, Statement (e) is NOT TRUE.
