Question

Twice a number (x) is equal to 34 less than 4 times the number on any given Tuesday in a month that ends in y. What is the number on the following Friday, which is 3 days later?

Answer 1

2x = 4x -34

34 =4x-2x

34 = 2x

x =34/2

x= 17

It means the number ,x, is 17.

Then from Tuesday to Friday is 3 days

So, the Friday of every month that ends in y is; 17 +3 = 20.

So the required Friday is 20.
