Question

One cow with 3 cows and 4 buffaloes together costs Rs. Bought for 1,16,000. He sold each cow at a loss of 5% and a buffalo at 7.5% profit. The total selling price of all was Rs. 1,20,000. However, how much per cow?​

Answer 1

Answer:

3c+4b=116000 -------(1)

5%less means 19/20

7.5% gain means 43/40

(3c*19/20)+(4b*43/40)=120000-------(2)

multiplay 43/40 to eqn 1

then

b tersms cancel

(3c*43/40)-(3c*19/20)=124700-120000

15c/40=4700

c=12533.33
