Question

A trader bought two articles for Rs 40,000
each. If he sold them at a profit of 5% on the
first article and a loss of 10% on the second
article, find his overall profit or loss per cent.​

Answer 1

$\huge\mathcal\pink{ANSWER:-}$

In case 1,

C.P = rs 40000

Profit% = 5 %

S.P = (100 + gain%) / 100 * CP

= 105/100 * 40000

= 42000

In Case 2,

C.P = rs 40000

Loss% = 10%

S.P = (100 - loss%) / 100 * CP

= 90/100 * 40000

= 36000

So total CP = rs 2 * 40000

= rs 80000

Total SP = 42000 + 36000

= 78000

So,loss = C.P - SP

= 80000 - 78000

= 2000

Loss% = loss/cp * 100

= 2000 / 80000 * 100

= 2.5%
