Question

the price of gold reduced by 20% if the redused price is 800rs per gram original price per gram

Answer 1

Let the original price be Rs a

Original price - 20 % of original price = Reduced price

=> a - 20a/100 = 800

=> 80a/100 = 800

=> a = 80000/80

=> a = 1000

Original price = Rs 1000

Answer 2

let original price be X.

therefore , x - 20a/100 = 800

= 100x - 20x = 80000

= 80x = 80000

= x = 1000
