At what time are the hands of clock at 48o angle between 4 and 5 o’clock? |
4:13\(\frac{1}{11}\) o’clock 4:32\(\frac{8}{11}\) o’clock 4:30\(\frac{8}{11}\) o’clock 4:10\(\frac{10}{11}\) o’clock |
4:13\(\frac{1}{11}\) o’clock |
T = \(\frac{60}{55}\)(5 × H ± distance) 1 min = 6o = \(\frac{60}{55}\)(5 × 4 ± 8o) 48o means 8 minutes = \(\frac{12}{11}\)(20 ± 8) Take both sign respectively, \(\frac{12}{11}\) × 12 = 13\(\frac{1}{11}\) \(\frac{12 × 28}{11}\) = 30\(\frac{6}{11}\) So, correct answer is option (A). |
