wrong (Question: 99775.0 )

2nd equation me 16000 kaise maan liya diya hi nai hai

Question:
The cost of 2 sarees and 4 shirts is \(\unicode{x20B9} \)16000 while 1 saree and 6 shirts cost the same. The cost of 12 shirts is :
Options:
A) \(\unicode{x20B9} \)12,000  
B) \(\unicode{x20B9} \)24,000
C) \(\unicode{x20B9} \)48,000
D) \(\unicode{x20B9} \)25,000
E) Can’t be determined
Solution:

Ans (b) Let cost of 1 saree = Rs. x

cost of 1 shirt = \(\unicode{x20B9} \) y

∴ 2x + 4y = 16000 …(i)

and x + 6y = 16000 …(ii)

Multiplying (ii) by 2 and subtracting (i) from it, we get,

8y= l6000⇒ y= 2000

∴ cost of 12 shirts = = (\(\unicode{x20B9} \)2000 ×12)

= \(\unicode{x20B9} \)24000
