at first the average mass some durians was 3.4kg.when 2 durians were added the aevrage mass of the 2 durians was 1.3kg was added
LekaFEV [45]

We conclude that the initial number of durians is 12.

<h3>How many durians were there at first?​</h3>

Let's say that initially, we had N durians, such that these N durians have an average mass of 3.4kg.

When 2 durians  (with an average mass of 1.3kg) more are added, the new average mass is given by:

(N*3.4kg + 2*1.3kg)/(N + 2)

And we know that the above amount is equal to 3.1kg, then we can write:

(N*3.4kg + 2*1.3kg)/(N + 2) = 3.1kg

Now we can solve this equation for N:

(N*3.4kg + 2.6kg) = 3.1kg*(N + 2)

N*(3.4kg - 3.1kg) = 6.2kg - 2.6kg

N*(0.3kg) = 3.6kg

N = (3.6kg)/(0.3kg) = 12

We conclude that the initial number of durians is 12.

How could you find the number of different arrangements of 6 letters in a computer password?
scoray [572]

Solution: If we are allowed to use only lower case letters, then we have 26 letters available with us. From these 26 letters the number of different arrangements of 6 letters is:

26^{6}=308915776

Now if we are allowed to use only upper case letters, then we have 26 letters available with us. From these 26 letters the number of different arrangements of 6 letters is:

26^{6}=308915776

if we are allowed to use both  upper case and lower case letters, then we have 52 letters available with us. From these 52 letters the number of different arrangements of 6 letters is:

52^{6}=19770609664&#10;
