Question

A man purchased computer at Rs. 10,000. He further got it repaired in
Rs. 1000. He sold it with 10% profit. What is the selling price?
(a) 12200
(b) 11000
(c) 12100
(d) 11100​

Answer 1

CP of a computer = Cost of computer + Expenses on repair = 10000 + 1000 = Rs.11000

So, CP of computer = Rs.11000

Profit % on computer = 10%

$sp = cp \times ( \frac{100 + p}{100})$

$sp = 11000 \times ( \frac{100 + 10}{100 })$

$sp = 11000 \times ( \frac{110}{100})$

$sp = 1100 \times 11$

sp = 12100

Therefore SP of a computer is (c)12100.
