Question

the cost of 2 tables and 5 chairs is ₹2300. If a table costs ₹30 more than a chair, find the price of each​

Answer 1

Answer:

The Cost of Chair=320

the cost of table=350

Step-by-step explanation:

tables t and chair C say..

2t+5C=2,300.......(1)

t-c=30....... .(2)

if we love 1 and 2 equation

2(30+c)+5C=2,300

7C=2,300-60

C =2,240/7

C=Rs.320

C value substitute in equation 2

t-320=30

t=320+30

=350

the cost of a table=Rs.350

Answer 2

Answer:

The price of 2 table is 700rs and that of 5 chairs is 1600rs

Step-by-step explanation:

let x be table and y be chairs...

:2x+5y=2300--------(1)

from the second condition,

:x=y+30-----(2)

substitute value of x in (1)

:2(y+30)+5y=2300

:2y+60+5y=2300

:7y=2300-60

:7y=2240

:y=2240/7

:y=320

substitute value of y in (2)

:x=350

now,substitute value of x and y in equ(1).....

:table =700

:chair=1600
