A dealer buys a wristwatch for Rs 225 and spends Rs 15 on its repairs. If he sells the same for Rs 300, find his profit percent.

Answer:

We know the cost price of wrist watch = Rs 225

Cost of repairing = Rs 15

Total cost = Rs 225 + Rs 15 = Rs 240

Selling price of watch = Rs 300

By using the formula,

Gain = selling price – cost price

= Rs 300 – Rs 240

= Rs 60

By using the formula,

Gain % = (gain/cost price) × 100

= 60/240 × 100

= 25%

"hello students i am rita your math
leader tutor
and the today's question is a dealer
buys a wrist watch for rupees 225
and spent rupees 15 on its repairs
if he seems the same for rupees 300
find his profit percent in this question
cp is given to us rupees 225
but he spends 15 rupees more
on its repairing so we add these 15
rupees to the cost price
then we got rupees
to 40 rupees and the ceiling price
is rupees 300
so the profit percent is prof first of
all we find the profit
sp minus cp that is 300
minus 240 is equal to
60 now the profit percent is
profit by cp into 100
so profit is 60 and cp is 240 into 100
now zero cancel out each other six ones
are six fours
and four twenty fives are it means
the answer is 25 percent this is our
answer
