Question

A Man buys two mobiles for Rs. 2,000 each. He sells one of

them at 10% profit and other at 5% loss, what percent of
profit or loss is there in the total transaction?​

Answer 1

2.6%

Explanation:

CP of each phone =2000

total cp = 4000

in 1st case

profit = 10 %

so,sp = cp + 10 % of xp

= 2000 + 10/100 ×2000

= 2200

in 2and case

loss =5%

so sp=cp - 5% of cp

=2000 - 5/100 × 2000

=1900

so total sp = 4100

so profit % = sp - cp/cp ×100%

= 2.5
