Question

A bag contains 25 paise, 10 paise and 5 paise coins in the ratio 1 : 2 : 3. If the total value of the coins is Rs. 36, the number of 25 paise coins is

Answer 1

see x+2x+3x=36 so,x=6 or 36/(1+2+3)=6,so number of 25 paise coins is 24 but the ans wer is 60?.

Answer 2

25x/100+10*2x/100+5*3x/100=36
60x/100=36,so x=60

Answer 3

how if rs6 is the value of 25 paise coins.the total coin value=36 bcoz,10 is rs12 and 18rs for 5 paise

Answer 4

so the number of 25 coins is 24 only ?.25 paise to make one rupee is 4 so 4*6=24

Answer 5

lets start from scratch

Answer 6

say, there are "a" 25 paise coind, "b" 10 paise coins, and "c" 5 paise coins in the bag :

25a + 10b + 5c = 3600

Answer 7

fine with that equation ?

Answer 8

yes so a=60 coins,120 for10,180 for5

Answer 9

so there value bcomes 3600 right?

Answer 10

exactly !

Answer 11

but they gave 36 only for total value.this doesnt match

Answer 12

36 rupees = 3600 paise

Answer 13

notice that we're measuring in paise on left hand side

Answer 14

so right hand side becomes 3600

Answer 15

if you want to measure in rupees, you would get :

0.25a + 0.1b + 0.05c = 36

Answer 16

because 25 paise = 0.25 of a rupee
10 paise = 0.1 of a rupee
5 paise = 0.05 of a rupee

Answer 17

in short :
1 paise = 0.01 of a rupee

Answer 18

or :
1 rupee = 100 paise

so, 1/100 rupee = 1 paise
which is same as :
0.01 rupee = 1 paise

Answer 19

all above are same ^^
just messing with the `paise <-> rupee` conversion

Answer 20

if we get 24 coins of 25 paise this also will be correct?

Answer 21

they asked for 25 paise coins so 24 only.not for one paise coin..it still confusing question.i understood it taken for paise

Answer 22

lets see :

25 paise : 24 coins
10 paise : 24*2 coins
5 paise : 24*3 coins

Answer 23

that means :

25 paise : 24 coins = 6 rupees
10 paise : 24*2 coins = 4.8 rupees
5 paise : 24*3 coins = 3.6 rupees
-------------------------------------

Answer 24

you won't get a total of 36 rupees, so 25 paise coins can NOT be just 24 okay ?

Answer 25

25 paise coins have to be 60

Answer 26

yes.but little twisted question

Answer 27

got it!

Answer 28

agree, here is the complete solution in one place :


say, there are "a" 25 paise coins, "b" 10 paise coins, and "c" 5 paise coins in the bag :
25a + 10b + 5c = 3600 ------(1)

we're give n :
a : b : c = 1 : 2 : 3
so b = 2a, c = 3a
substitute these in equation (1), you get :
25a + 10(2a) + 5(3a) = 3600
60a = 3600
a = 60

Answer 29

good:)
