b. 44
c. 39
d. 40​

Answer 1

Answer:

Option B: 44

Step-by-step explanation:

If we consider C for Chairs and T for Tables.

5C + 2T = 5820 ........(1)

2C + T = 2640.......(2)

(2) X 2

4C + 2T = 5280 .......(3)

(1) - (3)

5C + 2T = 5820

4C + 2T = 5280

--------------------------

C            =  540

From (2),

T = 2640 - (2 x 540)

T = 1560.

Hence,

Difference between one table and two chairs is,

= 1560 - ( 2 x 540)

= 480

Percent : 480/1560 x 100 = 44.444%(approx. 44).

Hence,

The cost of one table is 44 percent more than the cost of 2 chairs .
