Question

Ganesh sold a watch at a profit of 15%. Had he bought it at 10% less and sold it for Rs 28 less, he would have gained 20%. Find the cost price of the watch.​

Answer 1

Step-by-step explanation:

Description for Correct answer:

Let the cost price of table = Rs.x.

Then, selling price with 15% gain

= (100+Gain%)×CP100(100+Gain%)×CP100

= (100+15)%×CP100(100+15)%×CP100

= 115×x100=Rs.115x100115×x100=Rs.115x100

New CP = (100−25%)×CP100=Rs.75x100(100−25%)×CP100=Rs.75x100

New SP = Rs.(115x100)−60Rs.(115x100)−60

Now, according to the question,

(115x100−60)−75x10075x100×100=32(115x100−60)−75x10075x100×100=32

115x−6000−75x10075x100×100=32115x−6000−75x10075x100×100=32

40x−600075x×100=3240x−600075x×100=32

40x−60003x×4=3240x−60003x×4=32

160x - 24000 = 96x

160x - 96x = 24000

64x = 24000

x = Rs.375

The cost price of table is Rs.375.
