This one was found on an Egyptian manuscript dated to the 17th century (BCE):
The sum of a number, 2/3 of that number, ½ of that number, and 1/7 of that number is 33. What is that number
Answer :
Calculation of Number :
Let The number be x
Given
x + (2 / 3)x + (1/2) x + (1/7)x = 33
Taking Least Common Multiple of 3 , 2 , 7 which comes out to be 42 (3 * 2 * 7)
42x + (2 * 14)x + (1 * 21x)(1 * 6x) = 33 * 42
42 x + 28 x + 21x + 6x = 1386
97x = 1386
==>x = 1386 / 97 or 14.2886597938
