Question

A farmer sold two cows for 20000 each .if he gain 5% on the first deal and loss 10% on the second deal .find the overall gain or loss percent.

Answer 1

For the first cow

SP= Rs. 20,000

Profit- 5%

CP= 100/100+P% Multiply by SP

CP= 100/105 (After cutting with 20000=21) Multiply by 20000 (After cutting with 105= 4000)

CP=400000/21

CP=Rs. 19047.62 (Approx.)

SECOND COW

SP=Rs.20000

Loss=10%

CP=100/100-Loss

CP=100/90(After cutting with 20000=9) Multiply by 20000(After cutting with 90=2000)

CP=200000/9

CP=Rs.22222.22( Approx.)

Now,

Total CP= Rs.19047.62+Rs.22222.22

=Rs.41269.84

Total SP=Rs.20000+Rs.20000=Rs.40000

:. CP>SP Hence, It's a loss.

Loss=CP-SP

=Rs.41269.84-Rs.40000

=Rs.1269.84
