Question

A man bought good worth Rs.72,000 and sold half of them at a gain of 10%. At what gain percent must he sell the remainder so as to get a gain of 25%on the whole

Answer 1

Answer:

Step-by-step explanation:

Let the required gain  percent be  x%

Then , (110% of 3000) + [(100 + x)%  of 3000] =  125%  of 6000

⇒   (110100×3000)+[(100+x)100×3000]= 125100×6000

⇒  30(100+x)= 4200     ⇒ 100+x = 140    ⇒  x = 40%.
