Harry purchased some fruits and sold 1/2 of them at a gain of 60% and 1/4 of them at a
gain of 20%, the rest were spoiled. Find his gain or loss percent on the whole.

Respuesta :

Answer:

40% gain.

Step-by-step explanation:

Suppose he bought 100 fruit at a cost of $40.

He sold  1/2 ($20 ) for 20 * 1.6 = $32.

He sold 1/4 ($10) for 10*1.2 = $24.

Total revenue  = $56 dollars so he made 56 - 40 = $16 profit.

percent gain = 16 * 100 / 40

= 40 %.
