Rats   11 years AGO

Let C.P. of rice =R
and C.P. of wheat=W
4R+10W=3600......(1)
10% gain on wheat=2R/5
2%loss on wheat=W/5
(2R/5)-(W/5)=120
W=2R-600.....(2)
On solving (1)and (2)
we get R=400
So, C.P. of one bag of rice=Rs400.......Ans

Let the cost price (C.P.) of 1 bag of rice be Rs x
and the cost price (C.P.) of 1 bag of wheat be Rs y
Then the cost price (C.P.) of 4 bags of rice = Rs 4x
and the cost price (C.P.) of 10 bags of wheat = Rs 10 y
Given:
Total C.P. = Rs 3600
⇒ 4x + 10y = 3600
⇒ 2x + 5y = 1800 ......... (1)


Thus, overall gain = Rs 120

Putting the value of y on (1) we get
2x + 5(2x – 600) = 1800
⇒ 2x + 10x – 3000 = 1800
⇒ 12x = 3000 + 1800 = 4800

⇒ y = 2×400 – 600 = 800 – 600 = 200
Hence, the C.P. of one bag of rice = Rs 400
and the C.P. of one bag of wheat = Rs 200

Answer is 400.
let c.p of rice is and 'x' wheat is 'y'
4x+10y=3600
4.4x+9.8y=3720
solving this we get cost price of 400.

Nilla sai sumanth   11 years AGO

let cost of 4 rice bags=x
cost of 10 wheat bags=y
x+y=3600
10% gain on rice bags=+0.1x
2% loss on wheat bags=-0.02y
total sp= x+0.1x+y-0.02y
profit =sp-cp=120
(x+0.1x+y-0.02y)-(x+y)=120
0.1x-0.02y=120
x+y=3600
by solving, we get x=1600 & y=2000
therefore cost of one rice bag is 1600/4=400

Suppose cp of one bag of rice is R
and cp of one bag of wheat is W
then
4R+10W=3600 .......(i)

now 10% gain on 4R means 4.4R [4+(4*10/100)]
and 2% loss in 10W means 9.8W [10-(10*2/100)]
and he gains 120 rs. means total sp=3600+120 ie; 3720
so new equation is
4.4R+9.8W=3720 .......(ii)

on solving equation i & ii, we get
R=400;
W=200;

From the option if we are taken c.p of rice is 400 means then 4kg rice c.p is 1600 and remaining 2000 is c.p of wheat.for rice he sells 10% profit means then Rs.160 is profit on rice then wheat is sold for 2% lose then Rs.40 is lose on wheat so net profit is Rs.120(160-40=120)

Let the cost price (C.P.) of 1 bag of rice be Rs x

and the cost price (C.P.) of 1 bag of wheat be Rs y

Then the cost price (C.P.) of 4 bags of rice = Rs 4x

and the cost price (C.P.) of 10 bags of wheat = Rs 10 y

Given:

Total C.P. = Rs 3600

⇒ 4x + 10y = 3600

⇒ 2x + 5y = 1800 ......... (1)

Thus, overall gain = Rs 120

Putting the value of y on (1) we get

2x + 5(2x – 600) = 1800

⇒ 2x + 10x – 3000 = 1800

⇒ 12x = 3000 + 1800 = 4800

⇒ y = 2×400 – 600 = 800 – 600 = 200

let the C.P of 4 bags of rice =x
then x+ C.P of 10 bags of wheat =3600
C.P of 10 bags of wheat= Rs(3600-x)
10% of (4 bags of rice)- 2% of(10 bags of wheat) =120
so
10% of x -2% of (3600-x)=120
x/10 - 2(3600-x)/100 = 120
(10x-7200+2x)/100 = 120
12x - 7200 = 12000

Let us say the C.P. of 4 rice bags be Rs.x.

Total gain is Rs.120.So,Total S.P.-total C.P.=gain

Let the cost price (C.P.) of 1 bag of rice be Rs x

Then the cost price (C.P.) of 4 bags of rice = Rs 4x
and the cost price (C.P.) of 10 bags of wheat = Rs 10 y

Given:
Total C.P. = Rs 3600
⇒ 4x + 10y = 3600
⇒ 2x + 5y = 1800 ......... (1)

Gain on rice: 4x*10%= 2/5x
loss on wheat: 10y*2%= y/5

Thus, overall gain = Rs 120

Adding gain of rice+ loss of whear = overall gain
Which results to
2x-y=600
y= 2x - 600.

Putting the value of y on (1) we get
2x + 5(2x – 600) = 1800
⇒ 2x + 10x – 3000 = 1800
⇒ 12x = 3000 + 1800 = 4800

2x + 5y = 1800-----(1)

Gain on rice=4x*10/100=2x/5
loss on wheat=10y*2/100=y/5

Thus, overall gain = Rs 120
2/5x-y/5=120
2x-y=600
y=2x-600------(2)

Putting the value of y on (1) we get
2x + 5(2x – 600) = 1800
2x + 10x – 3000 = 1800
12x = 3000 + 1800 = 4800

y = 2×400 – 600 = 800 – 600 = 200
Hence, the C.P. of one bag of rice = Rs 400

let rice bag be of x rs
n wheat be of y rs
=> 4x+10y=3600....(A)
sp of rice= 4*x(1+10/1000)...1
sp of wheat = 10*y(1-2/100)....2
=>profit= sp-cp
4.4x+9.8y-(4x+10y)=120...(B)
solving A & B
x=400 y=200
rice cost/bag=400rs

let cp of one bag of rice is x and one bag of wheat is y.
then 4x+10y=3600---(1)
again, 4x*(10/100)-10y*(2/100)=120---(2)
on solving these two we get x=400.

let cost price of each rice bag be x and that of each bag of wheat be y.
4x+10y=3600.........(1)
profit=s.p-c.p.........(2)
here profit=120.........(3)
s.p=1.1*4x+.98*10y.......(4)
as rice is sold with 10% profit and wheat with 2%
loss .
from eqn 1,2,3 and 4
.4x-.2y=120........(5)
from equation 1 and 5 we have
x=400(cp of rice)
y=200(cp of wheat)

4x+10y=3600,......eq1
4(1.1x)+10(0.98y)=3720 .....eq2
Solve 1&2(by multiplying eq1 by 98 and eq2 by 100)
x=400, then y=200 then apply in eq1 3600=3600
so ans is 400

Let the cost price (C.P.) of 1 bag of rice be Rs x

and the cost price (C.P.) of 1 bag of wheat be Rs y

Then the cost price (C.P.) of 4 bags of rice = Rs 4x

and the cost price (C.P.) of 10 bags of wheat = Rs 10 y

Given:

Total C.P. = Rs 3600

⇒ 4x + 10y = 3600

⇒ 2x + 5y = 1800 ......... (1)

Thus, overall gain = Rs 120

Putting the value of y on (1) we get

2x + 5(2x – 600) = 1800

⇒ 2x + 10x – 3000 = 1800

⇒ 12x = 3000 + 1800 = 4800

⇒ y = 2×400 – 600 = 800 – 600 = 200

Hence, the C.P. of one bag of rice = Rs 400

Preety Soni   11 years AGO

let cost price of one rice bag is x and one wheat bag is y..
4x+10y=36000......(1)
He sells rice at 10% gain and wheat 2% loss and thus he gained Rs.120
so,
selling price of rice is 4x+4x/10
selling price of wheat is 10y-y/5
and total selling price= 3600+120=3720
another equn is form...
4x+4x/10+10y-y/5=3720
44x+98y=37200......(2)
by solving equn 1 and 2 we get
x= 400
so, C.P. of one bag of rice=400... ans

let rice price is 400,and wheat price is 200.then, 4 bag rice price -1600 and 10 bag wheat -2000. 10%of gain =160,2%loss=40.
it means 120 he gains. so c.p. of 1 bag of rice=400

let x as price of rice , y as wheat
from given 4x+10y=3600
4(x+10x/100)-10(y-2y/100)=3600+120
by solving these two eqn we get x=400 y=200
