Explanation

To solve for X, subtract 8 from both sides of the equation:

3X + 8 - 8 = 20 - 8

3X = 12

Next, divide both sides by 3:

3X / 3 = 12 / 3

X = 4

So, the value of X is 4!

Explanation

Initially, the pizza is divided into 12 equal slices, and 4 slices are eaten, leaving:

12 - 4 = 8 slices

To find the fraction of the pizza that remains, divide the number of remaining slices by the total number of slices:

8 ÷ 12 = 2/3

So, 2/3 of the pizza remains.

To find the number of good apples, you can subtract the number of bad apples from the total number of apples.

First, calculate the number of bad apples:

2/9 of 27 = (2/9) × 27 = 6

So, there are 6 bad apples.

To find the number of good apples, subtract the bad apples from the total:

27 - 6 = 21

Therefore, there are 21 good apples.

Explanation

"A" sold the pen for Rs. 180.

This was Rs. 60 less than what "A" paid for it, so the cost price was:

Rs. 180 (selling price) + Rs. 60 (loss) = Rs. 240 (cost price)

To find the loss as a percentage of the cost price, divide the loss by the cost price and multiply by 100:

Loss = Rs. 60

Cost price = Rs. 240

Loss percentage = (Loss ÷ Cost price) × 100 = (60 ÷ 240) × 100 = 25%

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

• Calculate the expression inside the parentheses: 2^2 = 4
• Raise 4 to the power of 3: 4^3 = 64
  

Explanation

Initially, the whole cake is 8/8 (which is equal to 1).

If 2/8 part of the cake has been eaten, that means 2/8 has been subtracted from the whole cake.

So, the remaining fraction of the cake is:

8/8 - 2/8 = 6/8

Now, we can simplify the fraction 6/8 by dividing both numerator and denominator by 2, which gives us:

6/8 = 3/4

Explanation

The pattern alternates between multiplying by 2 and subtracting 8:

14 × 2 = 28

28 - 8 = 20

20 × 2 = 40

40 - 8 = 32

32 × 2 = 64

64 - 8 = 56

Explanation

To find the market price of the car without tax, we need to remove the 6% sales tax from the total price of Rs. 154,431.40.

Let the market price of the car be P.

Including 6% sales tax, the equation is:

P + 0.06P = 154,431.40

1.06P = 154,431.40

Now, solve for P:

P = 154,431.40/1.06

P = 145,690

So, the market price of the car without tax is Rs. 145,690.
