Question

Joe purchased 20 apples from a supermarket for rs 180 at a discount of 10 percent .how much will a dozen apples cost Him if he does not avail any discount

Answer 1

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
