Question

a fruiterer bought 144 pineapples at sh.100 for every 6 pineapples. she sold some of them at sh.72 for every 3 and the rest at sh.60 for every 2. if she made a 65% profit , calculate the number of pineapples she sold at sh.72 for every three.

Answer 1

$\frac{144}{6} \times 100 = 2400$

Profit of 65%

Profit of 65%If 2400 = 100%

Profit of 65%If 2400 = 100%? = 165%

$\frac{2400 \times 165}{100} = 3960.(selling \: price)$

Let the number sold for every three be x

Let the number sold for every three be xThe number sold for every two is 144 – x

$s.p) \frac{x}{3} \times 72 + \frac{144 - x}{2} \times 60$

= 24+30(144−)=3960

= 24+30(144−)=396024+4320−30=3960

= 24+30(144−)=396024+4320−30=396024−30=3960−4320

$\frac{ - 6x}{6} = \frac{ - 360}{ - 6}$

=60

=60So the pineapples sold at sh. 72 for every three were 60.
