Answer 2

Answer:

answer = the shopkeeper has a total of 24 pend

Step-by-step explanation:

let the total number of pens = x

therefore-

$x = \frac{1}{3} x + \frac{1}{4} x + 10$

$x - \frac{1}{3} x - \frac{1}{4} x = 10$

$\frac{12x - 7x}{12} = 10$

$\frac{5x}{12} = 10$

$x = \frac{10 \times 12}{5}$

$x = \frac{120}{5}$

$x = 24$

total pens = 24
