Options
1) 30
2) 350
3) 25
4) 300

• 2) 350
  
  If cost of a CD=c and a Pen drive=p, then
  3c + 2p= 790 ----(i) &
  2c + 3p= 1110 ----(ii)
  On solving (i) & (ii), c=30, p=350

• 3cd+2pen = 790
  2cd+3pen=1110
  ..........................
  5cd+5pen=1900
  5(1cd+1pen)=1900/5 == 380

• If cost of a CD=c and a Pen drive=p, then
  3c + 2p= 790 ----(i) &
  2c + 3p= 1110 ----(ii)
  On solving (i) & (ii), c=75, p=320
  so, the ans is 320

• 3c + 2p = 790------(1)
  2c + 3p = 1110-----(2)
  solving both equation, we get p=350

• 3c+2p=790...(1)
  2c+3p=1110...(2)
  
  6c+4p=1580...(3)
  6c+9p=3330..(4)
  
  equ 3&4 is given by...
  
  5p=7650
  ans:p=350
