Question

a dealer bought 200 watches for rupees 800 each he sell 20 of them at gain of 5% at what price per watch must he sell the remaining watches as to gain 40 % on the whole

Answer 1

Answer:

43.88%

Step-by-step explanation:

total cost price 200×800=160000

total selling price (40% profit) 160000×1.4(140÷100) =224000

selling price for 20 watches

20×800×1.05( 105÷100)=16800

remaining selling price 224000-16800=207200

remaining 180 watches we should get that amount

cp for 180 is 180×800 =144000

difference of sp and cp for 180 watches are 207200-144000 =63200

profit % = (63200÷144000)×100

=43.88%

we can solve this with alligation mixture method also
