month on buying tea leaves for his chai shop. What was the reduced
price of tea? What was the original price of tea?​

Answer 1

Step-by-step explanation:

Suppose, purchased tea =y kg

Price of tea per kg=Rs. x

Discount 15 % per kg

=x−

100

15

×x=

100

85 x

A chaiwallah can by 2 kg extra with 15 % of discount.

But without discount, xy=14.....(i)

And (x−

100

15 x

)(

100

85 x

)(x−2)=45 .........(ii)

By solving equation (i) and (ii):

⇒

100

85

(45)+

100

85×2x

=45

⇒x=

2×85

45×15

=3.97 per kg

So, the reduced price =

100

85

×3.97 per kg
