The cost of 2 sarees and 4 shirts is ₹ 16000 while 1 saree and 6 shirts cost the same. The cost of 12 shirts is

Let cost of one saree and shirt be x and y, respectively.
2x + 4y = 16000 ....(i)
x + 6y = 16000 ....(ii)
On multiplying Eq. (ii) by 2 and subtracting from Eq. (i). we get
2x + 4y = 16000
2x + 12y = 32000
-------------------------
-8y = -16000
∴ y = 2000
Putting the value of y in Eq. (ii), we get
x +6 x 2000 = 16000
∴ x = 4000
∴ Cost of 12 shirts = 12y
= 12 x 2000 = ₹ 24000
