Goods were bought for Rs.600 and sold the same day for Rs.650.25 at a credit of 9 months and still there was a gain of 2%. the rate percent is:

OPtion

1) 19/3 %
2) 25/3 %
3) 8 %
4) 21/3 %
5) 7 %
6) 15/3 %
7) 13 %
8) 13/2 %
9) 23/3 %
10)None of these

Solution

SP = (102% of Rs.600) = Rs.(102*600 /100) = Rs.612
Therefore P.W. of Rs. 650.25 due 9 months hence is Rs. 612
or Rs. 38.25 is S.I. on Rs. 612 for 9 month
Therefore
Rste = (100* 38.25/ 612*(3/4))% = 8(1/3) % = 25/3 %

Option 2)

Correct Option: 2 Best Solution (25)

Gopal   9 years AGO

2% gain so Sold at 600+2%=612
Now rate of int. will be calculated with formula
S.I. = P*T*R/100
Here S.I.=650.25-612=38.25
P=612,
T=9/12=3/4
So with formula
R=25/3 %

SREENIVASA RAO PALLAPU   9 years AGO

total =600/-
let this amount after 9 months=600+interest= X
given X + profit(2%)=650.25
X+0.02X=650.25 => X= 637.5
so 600+interest = 637.5 => interest = 37.5
PTR/100=37.5 => 600*(9/12)*R/100 = 37.5
=> R=25/3 %

s.p=(102%600)=612
p.w=650.25
rate=650.25-612=38.25
rate%=38.25*100/(612*9/12)

Swagatam Kumar Das   9 years AGO

2% gain
So SP is 102*600/100 =612
So 612+ interest=650.25
so interest=650.25-612 =38.25
so % rate is = (38.25/(612*3/4))*100
=25/3%

ravi prakash   9 years AGO

s.p=102%of600
=612
so 9 month hence price will be 612
=650.25-612
=38.25
rate%=(s.i*100)/p*t
=(38.25*100)/612*(3/4)
25/3% ans

Anoop Tiwari   9 years AGO

Selling price(S.P.)=102% of 600(because of 2% gain)
=102/100*600
=612
S.I.=650.25-612=38.25
hence,38.25=(612*r *3/4)/100
hence r=3825/612*3/4=25/3%
so ans is b)25/3

Dhruvesh Zala   9 years AGO

S.p.=102% of 600 rs
=(102/100)*600=612
so 650.25-612=38.25 is S.I. on 612 0ff 9 month
so Rate=(100*38.25)/(612*(9/12))
=25/3

shekhar suman   9 years AGO

gain=2%
so present cp=600+2/100*600=612
interest=650.25-612=38.25
then, 38.25=612*r/100*9/12
=>r=25/3%

BHASKAR MANDAL   9 years AGO

S.P. = 102% of Rs. 600 =102x 600= Rs. 612.

Now, P.W. = Rs. 612 and sum = Rs. 650.25.

T.D. = Rs. (650.25 - 612) = Rs. 38.25

Thus, S.I. on Rs. 612 for 9 months is Rs. 38.25.

Rate = (100 x 38.25) / (612 * 3/4) = 25/3 %

satyam sharma   9 years AGO

let the rate % be "x"
gain= 600*2%=12
total amount after gain(p.w)=600+12=612
p.w. =100*650.25/(100+(3x/4))
612=100*650.25/(100+(3x/4))
x=25/3 %
so correct option is 2
