Answer 2

Question :

If due to 20% decrease in price of salt, one can buy 5 kg more in Rs. 200, then find the reduced price of salt per kg

Answer :

The reduced price of salt per kg is Rs.8

Let the original price of salt per kg. be = Rs. x

So, purchaser can buy ( 200 / x )kg.

Now, reduction price is 20%

The amount for Salt per kg. = x × 80/100=Rs.4x/5

Therefore purchaser can buy,

(200 / ( 4x/5)) = 250/x kg

∴250/x − 200/x= 5kg

⇒50/x= 5

⇒x=Rs.10

Hence the reduced price of salt per kg.

=Rs.10×80/100

=Rs.8/kg.

Therefore, the reduced price of salt per kg is Rs.8
