**Q.1 **Determine if the following are in proportion.

(a) 15, 45, 40, 120 (b) 33, 121, 9,96

(c) 24, 28, 36, 48 (d) 32, 48, 70, 210

(e) 4, 6, 8, 12 (f) 33, 44, 75, 100

**Ans.**

(a) Ratio of 15 and 45 = 15:45

= 1:3

Ratio of 40 and 120 = 40:120

= 1:3

Since, 15:45 = 40:120

Therefore, 15, 45, 40 and 120 are in proportion.

(b) Ratio of 33 and 121= 33:121

= 3:11

Ratio of 9 and 96 = 9:96

= 3:32

since, 33:121 ≠ 9:96

Therefore, 33, 121, 9 and 96 are not in proportion.

(c) Ratio of 24 and 28 = 24:28

= 6:7

Ratio of 36 and 48 = 36:48

= 3:4

since, 24:28 ≠ 36:48

Therefore, 24, 28, 36 and 48 are not in proportion.

(d) Ratio of 32 and 48 = 32:48

= 2:3

Ratio of 70 and 210 = 70:210

= 1:3

since, 32:48 ≠ 70:210

Therefore, 32, 48, 70 and 210 are not in proportion.

(e) Ratio of 4 and 6 = 4:6

= 2:3

Ratio of 8 and 12 = 8:12

= 2:3

since, 4:6 = 8:12

Therefore, 4, 6, 8 and 12 are in proportion.

(f) Ratio of 33 and 44 = 33:44

= 3:4

Ratio of 75 and 100 = 75:100

= 3:4

since, 33:44 = 75:100

Therefore, 33, 44, 75 and 100 are in proportion.

**Q.2 **Write True (T) or False (F) against each of the following statements:

(a) 16 : 24 :: 20 : 30 (b) 21: 6 :: 35 : 10

(c) 12 : 18 :: 28 : 12 (d) 8 : 9 :: 24 : 27

(e) 5.2 : 3.9 :: 3 : 4 (f) 0.9 : 0.36 :: 10 : 4
