$\huge \bold \green{question}$

If one-third of a number minus 5 is 8, then the number is

a) 39

b) 13

c) 42

d) 40

option a. 39

$\huge \bold \blue{solution}$

let the number be 'x'

If one-third of a number minus 5 is 8

$= > \frac{1}{3} \times x - 5 = 8$

Therefore

$\frac{1}{3} \times x - 5 = 8$

$= > \: \frac{x}{3} - \: 5 \: = 8 \\ = > \frac{x}{3} = \: 8 + 5 \\ = > \frac{x}{3} = \: 13 \\ = > x \: = \:13 \: \times \: 3 \\ = > x = \: 39$
