Answer 1

Step-by-step explanation:

cost of 100 bats is 400×100=40000₹

he gain 20% on the hole

so total selling price is

(40000+40000×20/100)₹

=48000₹

he sells 20 bats at a gain of 5%

so the selling price of 20 bats is

20.(400+400×4/100)₹

20×416₹=8320₹

so the selling price of remaining 80 bats is

(48000-8320)₹=39680₹

cost price of 80 bats is 80×400₹=32000₹

gain =(39680-32000)₹=7680

% of gain is7680×100/32000=24%
