Cost price of an article M is Rs. 600 less than that of

Solution

Let the cost price of N be Rs. ‘a’ Cost price of M = Rs. (a − 600) Marked price of M
= 1.5 × (a − 600)
= Rs. (1.5a − 900) Marked price of N
= 1.2 × a
= Rs. 1.2a Selling price of M
= 1.5a − 900 − 300
= Rs. (1.5a − 1200) Selling price of N
= 1.2a − 200 Profit earned by M
= 1.5a − 1200 − a + 600
= Rs. (0.5a − 600) Profit earned by N
= 1.2a − 200 − a
= Rs. (0.2a − 200) ATQ, 0.5a − 600 = 0.2a − 200 + 200 Or, 0.5a − 600 = 0.2a Or, 0.3a = 600 Or, a = 2000 Marked price of M
= 1.5 × 2000 − 900
= 3000 − 900
= Rs. 2,100
