Question

the price of a book is increased by 12% if it's increased price is 145.60 find the original price​

Answer 1

Answer:

142.745098

Step-by-step explanation:

Let original price be x.

Thus, (12% of x) + x = 145.60

=> (12x/100) + x = 145.60

=> 102x/100 = 145.60

=> 102x = 145.60*100 => 14560

∴ x = 14560/102 => 142.745098.

Thus, the original price is 142.745098 (can be Rs, $ or anything as its unit is not specified in the question.)
