## Answers

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

40/200=1/5=1:5

15/75=1/5=1:5

Thus, the above statement is true.

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

7.5/15=1/2=1:2

5/10=1/2=1:2

Thus, the above statement is true.

(c) 99 kg : 45 kg = Rs 44 : Rs 20

99/45=11/5=11:5

44/20=11/5=11:5

Thus, the above statement is true.

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

32/64=1/2=1:2

6/12=1/2=1:2

Thus, the above statement is true.

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

45/60=9/12=3/4=3:4

12/15=4/5=4:5

Thus, the above statement is false.
