A Microwave oven is sold in Hyderabad for Rs.M. A retailer, Elahi from Hyderabad went to Madras and bought it for 25% less (when compared to the price in Hyderabad). He spends Rs,1,000 on transport to bring it from Madras to Hyderabad. He sold it in Hyderabad for Rs.M making a profit of 10%. Find the value of M (in Rs.).

6,285.7

According to the question,

Price at Madras = M × 75% = 3M/4

According to the question,

(3M/4 + 1000) × 110% = M

= (3M/4 + 1000) × 110/100 = M

= (3M/4 + 1000) × 110 = 100M

= 82.5M + 110000 = 100M

= 17.5M = 110000

= M = 110000/17.5 = 6285.7
