Answer:

 130

Step-by-step explanation:

original price = ( 1- 2/100)

98/100x = 127.40

x= 127.40 x 100/ 98

= 12740/98

= 130

Answer 2

Let the original cost be ₹ x.

According to condition,

x-(2% of x) = 127.40

or, x-2x/100 = 127.40

or, 98x/100 = 127.40

or, 98x = 127.40×100

or, 98x = 12740

or, x = 12740/98

or, x = 130

Hence, the original cost of the lawnmower was ₹ 130.
