Here as there are no braces, operators will work as per their precedence.
division and multiplication has same precedence and addition and subtraction has same precedence. Also / and * has higher precedence then + and -.
Thus first % and * should operate, now they being of the same precedence, they will work from left to right order thus % will operate first and the * will work on its result.

Thus 36%6*3 -9 +1 => 6*3 -9 +1 => 18 -9 + 1=> 10

When do you have Rs.60

by 14 Comments

You are depositing Rs. 3 in First day and Rs. 3 in Second day in your account. And you are withdrawing Rs. 4 from your account in Third day. You do this repeatedly. When soon do you have Rs. 60?

After third day you will have Rs.2 in your account (3+3-4). So your account will gain Rs.2 every 3rd day.

Thus you would have reached Rs. 60 in (60/2)*3 = 90 days, but important thing to notice is that you are withdrawing Rs. 4 on every third day so your balance will reach Rs.60 mark earlier than that.

So, if we observe we will reach (60-6)=Rs.54 in (54/2)*3=81 days, and as you will deposit Rs.6 in next two days, you will reach Rs.60 in 83days.

Lets say initial price is X rs, price after 10% discount will be.

X – X*10/100 = 90X/100, final price is 9/10th of initial price.

Thus price after 10 times discount of 10% over and over will be X(9/10)^10 = 0.3486X.

While price after 65% discount will be 0.35X.

Thus it will be more beneficial to choose Second scheme.
