Step-by-step explanation:
Let’s assume, person starts with Rs x
After 1st temple visit, he is left with Rs (2x-100)
After 2nd temple visit, he is left with Rs (4x-300)
After 3rd temple visit, he is left with Rs (8x-700)
After 4th temple visit, he is left with Rs (16x-1500), which is zero (as he is left with empty pockets)
Hence he started of with x i.e. Rs 1500/16 i.e. Rs 93.75
Answer: Rs 93.75
