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

Arrange 7 men in alternative height

by 7 Comments

There are 7 people numbered as 1 to 7.
The number denotes their height.
Arrange them in a line in such a manner so that the line appears in alternative of their heights, I.e. one short then long, again short then long.
The condition is that, if one by one member(remove 1, then 2, then 3) from the line is omitted, the order of their height remains alternative.

When 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.
