Suvam fixed the price of a watch as Rs. 1200 and he sold it allowing a discoiunt of 15% and made a profit of Rs. 120. What was the cost price of the watch? Find it.​

Respuesta :

15% of 1200 = 180
1200-180= 1020

to find the cost price use the discounted price and take it away from the original, then use the profit take away the discounted price.

1020-120=900
the cost price of the watch is Rs. 900
