Answer 1

Answer:

(b) ₹ 20000 Because,

Step-by-step explanation:

Let the gross value of TV be ₹ x

Commission on TV = 10%

Price of the TV after deducting the commission = ₹ (x – 10% of x)

= (x – ((10/100) × x))

= (x – (x/10))

= (10x – x)/10

= (9x/10)

The price of TV after deducting the commission = ₹ 18000 = (9x/10)

= 18000 = x = (18000 ×10) / 9

= x = (2000 × 10)

= x = ₹ 20000

${}$

Answer 2

Gross value = Rs x - $\frac{x}{10}$

Rs18000

So, x - $\frac{x}{10}$ = Rs18000

$\frac{9x}{10}$ = Rs18000

So, x = $\frac{18000×10}{9}$

X= 20000

Then the gross value of TV is Rs.20000 .
