Question

one third of a number is subtracted from 3 times the number the result is 800​

Answer 1

SOLUTION:-

Given:

One third of a number is subtracted from 3times the number the result is 800.

Therefore,

Let 3 times= 3x.

$3x - \frac{1}{3}x = 800 \\ \\ = > 9x - 1x = 2400 \\ \\ = > 8x = 2400 \\ \\ = > x = \frac{2400}{8} \\ \\ = > x = 300$

Therefore,

The number is 3x = 3×300

=) 900

Hope it helps ☺️
