(b) 192

(c) 49

(d) 16

Step-by-step explanation:

(a) x:6::55:11

Product of extremes= Product of means

x×11=6×55

x= 6×55/11

x= 6×5

x=30

(b) 12:48:x

12:48::48:x

Product of extremes= Product of means

12×x=48×48

x= 48×48/12

x= 48×4

x= 192

(c) 25:35:x

25:35:35:x

Product of extremes= Product of means

25×x=35×35

x= 35×35/25

x= 7×7

x=49

(d) 12:24::8:x

Product of extremes= Product of means

12×x=24×8

x= 24×8/12

x= 2×8

x= 16
