@ikram002p

Answer 11

try this,
Let x = original price
1.25x = 400

x = 400 / 1.25

Answer 12

original price
x = 320

and the increase in price is 80 Rs

Answer 13

but this not price per kilo gram? right

Answer 14

this is the price for the original amount (more 20 kg )

Answer 15

ok but how will u get price/kg

Answer 16

there is a difference of 80 dollars, between the old price and the new price

Answer 17

and a difference of 20 kilograms

Answer 18

so 80 Rs / 20 kg = 4 Rs / kg price increase

Answer 19

this is orignal price?

Answer 20

no, the english is very important here

Answer 21

What is the increased price of rice per kilogram? 4 Rs/ kg

and also give original price: 320 Rs

Answer 22

we don't have to find the original price of rice per kilogram

Answer 23

i don't think we can find that, since we are not given the original amount of kg of rice

Answer 24

All you are given is that
Due to a 25 % increase in the price of rice per kilogram you are able to purchase 20 kg less than what you usually buy for Rs 400. The number of kg you usually buy is not given

Answer 25

ok i think we are done here, let me know if you have any questions

Answer 26

but the majority gave answer as Rs 5/-

Answer 27

and the initial price is given Rs 4/-

Answer 28

in book

Answer 29

what was the book answer?

Answer 30

the question does not ask for initial price. it asks what is the increase in price per kilogram of rice. the increase in price is 4 Rs

Answer 31

1 Indian Rupee equals
0.016 US Dollar

Answer 32

4 Indian Rupee equals 0.065 US Dollar so the price increase was 6.5 cents for a kilogram of rice

Answer 33

6 pennies and half a penny :)

Answer 34

since the price is rising by 25%,
consuption has to decrease by 20%
but their is an actual reduction in consuption by 20 kg

hence the orignal price is 100kg

money spent being

RS 400 ,the orignal price of rice is 4kg

Answer 35

price is not kg, thats weight

Answer 36

*RS 4/kg

Answer 37

why does consumption have to decrease by 20% ? i might be missing information about the problem

Answer 38

I only answered based on what I was given

Answer 39

sorry, what was the book answer exactly ?

Answer 40

I thought this was an algebra question

Answer 41

i also dont know consuption factor here

Answer 42

hmm

Answer 43

a rise in 6 cents probably wont stop a person from purchasing the same amount of rice

Answer 44

book gave only orignal price ,
i have to find increased price

Answer 45

here is the answer too
http://totalgadha.com/mod/forum/discuss.php?d=8885

Answer 46

here is i found on somesite

\("\)saving due to price reduction= 25% of 400 is 25* 400/100
this savings enable him to buy 20kg
and, cost of 20kg at the reduced price= 25*400/100
then cost of 1kg at the reduced price= 25*400/100*20
= Rs 5\(" \)


but i dont undertand this

Answer 47

one moment, reading

Answer 48

it seems like theres two different answers

Answer 49

if you assume that consumption has to decrease, then you get a different answer

Answer 50

so which one is correct

btw the link u gave gives initial price

Answer 51

i guess it depends on the assumptions of the person who made the question.
how did they figure out by what percentage consumption has to decrease?

Answer 52

this website also gets 4 Rs

Answer 53

they assumed 20 kg to be 20% decrease

Answer 54

so they assumed he initially bought 100 kg?

Answer 55

but this site gives RS 5/-

Answer 56

this site also gives 5 Rs

Price ratio = 1.25 = 5:4
Consumption ratio = 4:5 = 1/5 of original less than original
1/5 ~ 20 Kg
1 ~ 100 Kg
100 Kg ~ Rs 400
1 Kg ~ Rs 4
New Price = 4*1.25 = 5

A rise of 25% in the cost corresponds to a fall of 20% in the consumption, since the expenditure on the purchase is the same. Hence he gets 20% less which corresponds to 20kg less rice than the original. Hence he gets 80 kgs for 400 Rs. Hence new price = 400/80 = 5 Rs.

25% of 400 is 100

100 Rs - 20 kg

5 rs - 1kg

P.S. - Don't trust my methods.

saving due to price reduction= 25% of 400 is 25* 400/100
this savings enable him to buy 20kg
and, cost of 20kg at the reduced price= 25*400/100
then cost of 1kg at the reduced price= 25*400/100*20
= Rs 5

short cut---- If a man purchase X kg less in Y rs due to rate increased by R% then
New Price of Product = (R/100) * Y/X,,, Old Price= (R / 100+R) * Y/X....

@Anonymous @Anonymous
price up by 1/4, consumption down by 1/5,
1/5 = 20,
1 = 100 kg,
old price = 400/100 = 4
new price = 400/80 = 5

@manash9078 newton @manash90781.5k
if increase in price is 1/4(i.e. 25%), decrease in consumption= 1/5
so, (1/5)x=20
x=100
so, original price is Rs. 400/100=Rs.4
so, new price is rs.(4+1)=5
