Fast trick to solve number system

Q .The difference between (8 / 2)th of (8 / 3)th of a number and (7 / 5)th of (6 / 5)th of a number is 277

Let number be the x -

( 8 / 2 )th of (8 / 3) x - (7 / 5 )th of (6 / 5)x = 277

( 8 / 2 ) * (8 / 3) x - (7 / 5 ) * (6 / 5)x = 277

(64/6) x - (42/25)x = 277

(1600x - 252 x )/150 = 277

1348x /150 = 277

x = (277 * 150) / 1348

x = 30.823442136499

So the number is 30.823442136499.
