Rashid went to the book exhibition stall and asked the manager for a job as a salesman for the 7 days of the exhibition. The manager offered him a job. Rashid wanted to know how much money he will get if he works there. The manager said “Rashid, you have two options. Option 1 is that I will pay you ₹1000 for seven days. Option 2: I will pay you ₹ 10 the first day, ₹ 20 for the second day, ₹ 40 for the third day and so on doubling the wages of the previous day for the seven days. Rashid was in a fix. He did not know which choice is more profitable. Will you please help him to find which choice is profitable and by how much?

Answer:
in first option rashid will be payed = rs 1000
in second option
1rst day = rs 10
2nd = rs 20 ( as the amount is doubled)
3rd = rs 40 (as the amount is doubled)
4rth = rs 80 (as the amount is doubled)
5th = rs 160 ( as the amount in doubled)
6th = 320 (as the amount is doubled)
7th = 640(as the amount is doubled)
total money he gets in the second option is 10 + 20 +40 + 80 + 160 + 320 + 640 = 1270
1270 is greater than 1000
so, second option is profitable
