Answer 1

₹87.50

Step-by-step explanat:

Solutions

let the total number of money man have be X

when he entered temple 1

he have = ₹(2x - 100)

Again when he entered the temple 2

he have = ₹{2(2x - 100) - 100}= ₹(4x - 300)

Again

when he entered the tample 3

he have = ₹{2(4x - 300) - 100}= ₹(8x - 700)

Again

when he entered the tample 4

he have =₹{2(8x - 700)- 100 }= ₹(16x - 1500)

According to question

16x - 1500 = 0

X = ₹1500/16

X = ₹93.75
