Question

A reduction in 10% in the price of mango enable Vicky to buy 2 kg mango for rs.360. find the reduced price of KG and the original price per kg​

Answer 1

Answer:

180/- and 200/- per kg are the price after reduction and before reduction respectively.

Step-by-step explanation:

Let Original Price (O.P)=100

Reduced Price (R.P) =90

When it is 90% the actual cost (A.C) of mango became 360/- for 2 kg

So, when 1%  the A.C will be 4/-

For 100% the A.c will be 400/- for 2 kg

∴O.P = 200 for 1 kg

R.P= 180 for 1 Kg

Answer 2

ANSWER:-

Let us consider the problem.

Original price is Rs x per. kg.

New price is Rs 1.12x

since, Dealer gets 27kg. less for Rs. 24750 at new price.

hence,

$\frac{24750}{1.12x} + 27 = \frac{24750}{x}$

$= > 24750 + 30.4x = 24750 \times 1.12$

$= > 30.24 = 27720 - 24750$

$hence,$

$x = \frac{2970}{30.24} = 98.21$

$Therefore, \: new \: price \: is \: rs.98.21 \times 1.12 = rs.110$
