Question

Three numbers are in ratio 1 : 2 :3. The sum of their cubes is 7776. Find the number.

Answer 1

Let the numbers be x, 2x and 3x

According to the question

x³+ ( 2x )³ + ( 3x )³ = 7776

x³ + 8x³ + 27x³ = 7776

36x³ = 7776

x³ = 7776/36

x³ = 216

x = 6

Hence, First no, x = 6

Second number, 2x = 12

Third number, 3x = 18
