Answer:
1) 8 kg
2) 40 L
3) 4000
4) 40 girls
Step by step explanation :-
1) 7 kg : ....... = 14m : 6m
7 : x = 14 : 6
product of means = product of extremes
7*6 = x*14
x = 7*6/14
x = 8 kg
2) ...... : 63 L = 25 : 35
x : 63 = 25 : 35
product of means = product of extremes
x*35 = 63*25
x = 63*25/35
x = 40 L
3) 200 : 2.5 = ....... : 50
200 : 2.5 = x : 50
product of means = product of extremes
200*50 = x*2.5
x = 200*50/2.5
x = 4000
4) 65 : 100 = 26 : x
product of means = product of extremes
65*x = 100*26
x = 100*26/65
x = 40 girls
