Question

1. Two cows were sold at 1980 each, one at a profit of 10% and the other at loss of 10%. What was the cost price of each cow? ​

Answer 1

Answer:

1,800 and 2,200

Step-by-step explanation:

CP of the cow which had a loss of 10%

if the cow was sold at a 10% loss then the SP is 90% of CP

let the CP be x

90/100 * x = 1980

90x=198000

x=198000/90

x=2,200

CP of the cow which ha a profit of 10%

if the cow was sold at 10% profit then the Sp is 110% of CO

let the CP be y

110/100 *y = 1980

110y=198000

y=198000/110= 1800

Answer 2

Answer:

Step-by-step explanation:

First COW at 10% profit in 1200 Rs

Cost price of first COW = 1200/100+10 x 100=1000

Second fan at 100% loss in 1200 Rs

Cost price of second COW=1200/100-10 x 100

Total C.P of COWS = 2500 Rs

Total S.P of COWS = 2400 Rs

% Loss = 2500−2400/2500 x 100

%loss= 4%
