Correct Answer - Option 2 : 10 : 7

Given,

The cost price of 2 jackets and 3 shorts is Rs. 2200 and the cost price of 2 shorts and 4 jackets is Rs. 2400.

Calculations:

Let the cost price of one Jackets  = x Rs, the cost price of one shorts = y Rs

According to the question,

⇒ 2x + 3y = 2200      ...(1)

⇒ 2y + 4x = 2400

⇒ 2x + y = 1200      ...(2)

⇒ After solving these 2 equation,

⇒ x = 350 Rs. , y = 500 Rs.

⇒ Ratio = 500 : 350 = 10 : 7

∴ The required answer is 10 : 7
