Q. The cost of five chairs and three tables is Rs. 3110. cost of one chair is Rs. 210 less than cost of one table. What is the cost of two tables and two chairs?

Option
a. Rs. 1660
b. Rs. 1860
c. Rs. 2600
d. Cannot be determined

• chair value=x
  table value =y
  so
  5x+3y=3110
  -x+y=210
  so
  4x+4y=3320
  2x+2y=1660
  so ans is 1660

• Let x= Chair and y= Table
  A/c to question,
  5x+3y=3110 & x+210=y So, x=301 and y = 520
  So, 2chairs + 2 table= 2*310+2*520= 1660

• 5c+3t=3110;
  c=t-210;
  5(t-210)+3t=3110;
  5t-1050+3t=3110;
  8t=4160;
  t=520;
  so c=310;
  2t+2c=2(520)+2(310)=1660;
  cost of 2 tables and 2 chairs is 1660.

• correct answer is 1660......
  let the cost of one table be x then cost of one chair is x-210..
  as given that 5(x-210)+3x=3110-->x=520.....then cost of two tables and two chairs is 2*520+2*(520-210)=1660.
