At what time are the hands of clock at 90o angle between 3:15 to 4:00 o’clock?

3:32\(\frac{8}{11}\) 3:48\(\frac{2}{11}\) 3:42\(\frac{7}{11}\) 3:40\(\frac{10}{11}\)

3:32\(\frac{8}{11}\)

M =   \(\frac{60}{11}\)(H ± 3)  = \(\frac{60}{11}\)(3 ± 3)    So, taking +ve sign    =    \(\frac{60}{11}\)× 6   =  \(\frac{360}{11}\)    =   32\(\frac{8}{11}\)  minutes  So, correct option is (A).
