Answer:
x = Rs 20,833.33
the value of x is Rs 20,833.33
Step-by-step explanation:
Let x,y and z represent the price of the item initially, after one month and after two months respectively.
Given that;
after one month its label price is reduced by 20%
y = x - 20% of x
y = x - 0.20x
y = 0.80x ........1
after 2 months its reduced price is further reduced by 10% and then sold it for Rs 15000.
z = y - 10% of y
z = y - 0.10y
z = 0.90y ........2
Substituting equation 1 into 2;
z = 0.90(0.80x)
z = 0.72x
Also z = Rs 15000
So,
z = 0.72x = Rs 15000
0.72x = Rs 15000
x = Rs 15000/0.72
x = Rs 20833.33333333
x = Rs 20,833.33
the value of x is Rs 20,833.33

Answer:
The weight of 12 tennis balls = 691. 2 grams
Step-by-step explanation:
The weight of each tennis ball = 57.6 grams
So, the weight of 12 balls = 12 x ( weight of 1 ball)

= 691.2 grams
⇒12 balls weigh 691.2 grams
Hence, the weight of 12 tennis balls = 691. 2 grams
