Question

Aman sold two houses for Rs 20000 each. On one house he gains 20% and on the
other he loses 20 %. The loss or gain % in the whole deal is
(a) 3% loss (b) 4%loss (C) 4% profit (d) 3% profit.​

Answer 1

Answer:

First method :- use formula , % loss/profit = x + y + xy/100

for loss use negative sign and profit use positive sign

Here 20% profit , x = +20 and 20% loss = -20

Now, % loss/profit = 20 - 20 + (20)(-20)/100 = -400/100 = -4%

Here negative sign shows Malik loss 4%

Let seeling price of each table is 3000 Rs

Cost price , when he gains 20% = 3000/120 × 100 = 2500

Cost price , when he lost 20% = 3000/80 × 100 = 3750

Total cost price = 2500 + 3750 = 6250

Total loss = 6250 - 2 × 3000 = 250 Rs

Hence , loss % = 250/6250 × 100 = 4 %
