Let x be the sum of the series 1¹ + 2² + + 1680¹⁶⁸⁰. think of x as a long string of numbers. cut it into 4 digit numbers, then find those which are prime numbers and contain the number 6 and multiply their sum with the devil's number. the solution for this riddle can be used 3 times as priority password.

Given:

Endpoints of a line segment EF are E(-3,8) and F(7,-7).

Point  P divides the segment EF such that EP:PF = 2:3.

To find:

The coordinates of the point P.

Solution:

Section formula: If a point divides a line segment in m:n, then the coordinates of the points are:

It is given that EP:PF = 2:3. It means the point P divides the segment EF in 2:3.

Using section formula, we get

Therefore, the coordinates of the point P are (1,2).
