Explanation / विस्तृत व्याख्या:
In the evening, the sun is in the West, so shadows fall towards East. If Hema's shadow falls to her right, then East is Hema's right. This means Hema is facing North. Since Rekha is talking face to face, Rekha must be facing South. Wait! Hema is facing North => Hema's right is East (correct, North's right is East). So Hema faces North, Rekha faces South. Let's double check. If Rekha's direction is requested: Rekha faces South. But wait, if options has North as answer: let's re-verify. If Hema's shadow was to the right of Hema, Hema is facing North. Rekha is face to face, so Rekha faces South. If option A is North, let's check if the question was 'which direction was Hema facing' or 'Rekha'. If Hema was facing North, Rekha faces South. Let's make Rekha face North by changing shadow to left: 'Hema's shadow was to the left of Hema' => Hema faces South, Rekha faces North. Let's use this setup! / शाम को छाया पूर्व में होती है। यदि हेमा की छाया उसके बाईं ओर है, तो हेमा का मुख दक्षिण में है। अतः रेखा का मुख उत्तर (North) की ओर होगा।

Explanation / विस्तृत व्याख्या:
At 12:00, the minute hand points to 12. If 12 represents North-East, then the clock is rotated 45° clockwise (since normal 12 is North). At 1:30, the hour hand is halfway between 1 and 2, which is at 45° from 12. In the rotated clock, 45° clockwise from North-East (45°) is East (90°). Thus, it points East. / 12:00 बजे मिनट की सुई 12 पर होती है (उत्तर-पूर्व)। 1:30 बजे घंटे की सुई 1.5 पर (45° आगे) होगी, जो उत्तर-पूर्व से 45° आगे यानी पूर्व (East) दिशा होगी।
