Answer 2

Answer:

3) 2:3 : : 4:5

product of means= product of Extremes

3× 4( means) = 2×5( Extremes)

12 ≠ 10

so,2,3,4,5 are not in proportion

4) 3:5 : : 6: 10

product of means= product of Extremes

6×5( means )= 3×10( extremes)

30 = 30

so, 3,5,6,10 are in proportion

5) 3: x : : 9:12

product of means= product of Extremes

9× X (means) = 12 ×3 ( extremes)

9x= 36

X=36÷9

X= 4

sry I don't know 6,7,8
