Question

Price of sugar increased by 10%.as a result of which a person gets 1kg less in ru 88 find the original rate

Answer 1

Answer:

$Rs.8$

Step-by-step explanation:

Let,

The price of sugar is Rs. x=1.1 x

The new price per kg of sugar after increasing price by 10%=x=1.1x

Given,

That after increasing the price the person gets 1 kg sugar less in Rs

Therefore,

$→\frac{88}{x}-\frac{88}{1.1x}=1$

$→88×\frac{1.1x-x}{1.1x+x}=1$

$→\frac{88×0.1x}{1.1x²}=1$

$→x=\frac{88}{11}$     [11 canceled 88 by the number 8]

$→x=8$

Therefore,

Price of sugar per kg is RS.8

Hope it helps :-)
