Question

a 10% hike in price of salt forces a person to purchase 2kg less for rs110. find the new amd the original price of the salt​

Answer 1

Answer:

5,5.50

Step-by-step explanation:

let O. pr = x /kg

new prece 110% of x = 11x/10

110/x - 110/11x/10 = 2

110/x - 100/x = 2

10x = 2x^2 => x = 5

original price = Rs 5/kg & new price = 11×5/10 = Rs 5.50 /kg
