(a)3 to 6

(b) 2 to 8

(c) 5 to 11

(d) 10 to 1

(e) 12 to 9

(f) 12 to 6

Answer :

(a) 3 to 6 = 6 - 3 = 3 hour

In one revolution = 12 hour

No. of revolution = 3 / 12 = 1/4 revolution.

In one revolution = 4 right angle

\(\therefore \) 1/4 revolution = (1\4) × 4 = 1 right angle

(b) 2 to 8 = 8 - 2 = 6 hour

In one revolution = 12 hour

No. of revolution = 6 / 12 = 1/2 revolution.

In one revolution = 4 right angle

\(\therefore \) 1/2 revolution = (1\2) × 4 = 2 right angle

(c) 5 to 11 = 11 - 5 = 6 hour

In one revolution = 12 hour

No. of revolution = 6 / 12 = 1/2 revolution.

In one revolution = 4 right angle

\(\therefore \) 1/2 revolution = (1\2) × 4 = 2 right angle

(d) 10 to 1 I.e., 10 to 13 = 13 - 10 = 3 hour

In one revolution = 12 hour

No. of revolution = 3 / 12 = 1/4 revolution.

In one revolution = 4 right angle

\(\therefore \) 1/4 revolution = (1\4) × 4 = 1 right angle

(e) 12 to 9 I.e., 0 to 9 = 9 - 0 = 9 hour

In one revolution = 12 hour

No. of revolution = 9 / 12 = 3/4 revolution.

In one revolution = 4 right angle

\(\therefore \) 3/4 revolution = (3\4) × 4 = 3 right angle

(f) 12 to 6 = 6 - 0 = 6 hour

In one revolution = 12 hour

No. of revolution = 6 / 12 = 1/2 revolution.

In one revolution = 4 right angle

\(\therefore \) 1/2 revolution = (1\2) × 4 = 2 right angle
