Question

a farmer sold two bullocks for rs 18000 each.on one bullock he gained 20% and on other he lost 20%.find his total gain or loss

Answer 1

1st bullock
Selling Price = Rs. 18,000
Gain % = 20 %
using formula
Cost = (Selling price × 100) ÷ (100+Gain%)
         = (18000 × 100) ÷ (120)
         = 1,800,000÷120
         = 15,000

2nd Bullock
Selling price = Rs. 18000
Loss % = 20%
using formula
Cost price = (Selling price × 100) ÷ (100 - loss%)
                   = (18000 × 100) ÷ (100-20)
                   =1800000 ÷ 80
                   =22500

Total Selling price
1st bullock's Selling Price + 2nd bullock's Selling Price
18000 + 18000
36000

Total Cost price
1st bullock's Cost price + 2nd bullock's cost price
15000+22500
37500

Since Cost price is more than Selling price, it is a loss
Loss = 37500-36000
         =1500

Ans: 1500 loss
