Answer 2

$\Large{\textbf{\underline{\underline{According\;to\;the\;Question}}}}$

Assumption

Cost of 1 table is Rs. p

Also,

Cost of 1 chair is Rs. t

Then,

4p + 3t = 2250 ………... (1)

3p + 4t = 1950 ………... (2)

Multiply (1) by 3 and (2) by 4,

12p + 9t = 6750…………. (3)

12p + 16t = 7800 ……….(4)

Then,

Subtract (4) from (3),

-7t = - 1050

t = 1050/7

t = 150

Substituting value of y in (2),

3p + 4t = 1950

3p + 4(150) = 1950

3p + 600 = 1950

3p = 1950 - 600

3p = 1350

p = 1350/3

p = 450

So,

Cost of 2 chairs and 1 table :-

2t + p = 2 × 150 + 450

= 300 + 450

= ₹ 750

Therefore,

Cost of 2 chairs and 1 table = ₹ 750
