1.	Write true (T) or False (F) against each of the following statement:(a) 16 : 24 :: 20 : 30(b) 21 : 6 :: 35 : 10(c) 12 : 18 :: 28 : 12(d) 8 : 9 :: 24 : 27(e) 5 : 239 :: 3 : 4(f) 0.9 : 0.36 :: 10.4
Answer» (a) 16 : 24 :: 20 : 30 16/24 = 2/3, 20/30 = 2/3 Therefore 16 : 18 = 28 : 30 Hence, True (b) 21 : 6 :: 35 : 10 21/6 = 7/2, 35/10 = 7/2 Therefore 21 : 6 = 34 : 10 Hence, True (c) 12 : 18 :: 28 : 12 12/18 = 2/3, 28/12 = 7/3 Therefore 21 : 18 ≠ 28 : 12 Hence, True (d) 8 : 9 :: 24 : 27 As, 24/27 = (3 x 8)/(3 x 9) = 8/9 Therefore, True (e) 5 : 239 :: 3 : 4 As, 5.2/3.9 = 4/3 Therefore 5.2 : 3.9 ≠ 3 : 4 Therefore 0.9 : 0.36 = 10 : 4 Hence, True (f) 0.9 : 0.36 :: 10.4 0.9/0.36 = 90/36 = 10/4 Therefore 0.9 : 0.36 = 10.4 Hence, True

Write true (T) or False (F) against each of the following statement:(a) 16 : 24 :: 20 : 30(b) 21 : 6 :: 35 : 10(c) 12 : 18 :: 28 : 12(d) 8 : 9 :: 24 : 27(e) 5 : 239 :: 3 : 4(f) 0.9 : 0.36 :: 10.4

Answer»

(a) 16 : 24 :: 20 : 30

16/24 = 2/3, 20/30 = 2/3

Therefore 16 : 18 = 28 : 30

Hence, True

(b) 21 : 6 :: 35 : 10

21/6 = 7/2, 35/10 = 7/2

Therefore 21 : 6 = 34 : 10

Hence, True

12/18 = 2/3, 28/12 = 7/3

Therefore 21 : 18 ≠ 28 : 12

Hence, True

(d) 8 : 9 :: 24 : 27

As, 24/27 = (3 x 8)/(3 x 9) = 8/9

Therefore, True

(e) 5 : 239 :: 3 : 4

As, 5.2/3.9 = 4/3

Therefore 5.2 : 3.9 ≠ 3 : 4

Therefore 0.9 : 0.36 = 10 : 4

Hence, True

(f) 0.9 : 0.36 :: 10.4

0.9/0.36 = 90/36 = 10/4

Therefore 0.9 : 0.36 = 10.4

Hence, True
