Question

In spite of offering 20% discount on watch priced at rspees 300, a shopkeeper gains 20% what is the cost price of the watch​

Answer 1

Answer:

Rs.200

Step-by-step explanation:

Marked Price (MP) of watch = Rs.300

Discount = 20% = 20/100 × 300 = Rs.60

Selling Price (SP) = Rs.(300-60) = Rs.240

Gain = 20%

=> (100+20)% of CP = SP

=> 120% of CP = 240

=> 120/100 × CP = 240

=> CP = 240 × 5/6

=> CP = Rs.200
