Answer 1

Answer:

Rs. 120

Step-by-step explanation:

Let the original price without discount for the 20 apples be Rs.x

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 180

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9x = 20 × 10x

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9x = 20 × 10x x = 200

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9x = 20 × 10x x = 200The price of 20 apples = Rs. 200

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9x = 20 × 10x x = 200The price of 20 apples = Rs. 200So, the price of 1 apple = 200/20 = Rs. 10

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9x = 20 × 10x x = 200The price of 20 apples = Rs. 200So, the price of 1 apple = 200/20 = Rs. 10Price of a dozen apples(1 dozen = 12 apples)

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9x = 20 × 10x x = 200The price of 20 apples = Rs. 200So, the price of 1 apple = 200/20 = Rs. 10Price of a dozen apples(1 dozen = 12 apples) = Rs. (10×12)

Let the original price without discount for the 20 apples be Rs.xx - 10% of x = Rs. 180x - 10/100 × x = 180x - 1/10 × x = 180(10x - 1x )/ 10 = 1809x/10 = 180x = ( 180 × 10 )/ 9x = 20 × 10x x = 200The price of 20 apples = Rs. 200So, the price of 1 apple = 200/20 = Rs. 10Price of a dozen apples(1 dozen = 12 apples) = Rs. (10×12) = Rs. 120

Answer 2

Answer:

₹120

Step-by-step explanation:

Let the original price of the 20 apples be x.

According to the problem,

90%  of x = ₹180. (As 10% was discount)

90/100 * x = 180 (cut off the zeroes)

9/10 * x = 180

9x/10 = 180

9x = 180 * 10

9x = 1800

x = 1800/9 = ₹200.

Therefore, 1 apple = ₹10 (Unitary method)

Therefore, dozen ( = 12) = ₹10 * 12 = 120

Answer is ₹120
