A fruit-seller buys some oranges and by selling 40% of them he realises the cost price of all the oranges. As the oranges being to grow over-ripe, he reduces the price and sells 80% of the remaining oranges at half the previous rate of profit. The rest of the oranges being rotten are thrown away. The overall percentage of profit is

Solution:

Number of oranges bought = 100 (let)
C.P. = Rs.100 (let)
S.P of 40 oranges = Rs.100
∴ Gain percent =

{100-40}/{40}

× 100 = 150%
Remaining oranges = 60
Their 80 % =

{60×80}/{100}

= 48
These are sold at a profit of 75 %
∴ Their S.P. =

{48×175}/{100}

= Rs. 84
∴ Gain per cent = 84%
