Answer:
Let C.P of the table be x and C.P. of the chair be y. Then,
25x + 22y = 37920 … (i) ⇒
22x + 25y = 35400 … (ii) Adding (i) and (ii),
We get
47(x + y) = 73320 x + y = 1560 … (iii) Subtracting x = 1200 in (iii),
We get
1200 + y = 1560 y = 360. Therefore C.P. of 1 table = 1200 Therefore C.P. of 1 chair = 360.
