Q. Brother A and B had some in the ratio 4:5. They decided to buy a gift for their sister, sharing to cost in the ratio 3:4. After they bought, A spent two third of his amount while B is left with 145. Then the value of the gift is

• Brother A and B had some in the ratio 4:5 say 4x:5x.
  They decided to buy a gift for their sister, sharing to
  cost in the ratio 3:4 say 3y:4y.
  After they bought, A spent two third of his amount ( means 4x*2/3= 8x/3) while B is left with 145 means 5x-4y=145.
  value of gift =7y.
  solving, we get
  value of gift = Rs. 624.61

• Brother A and B had some in the ratio 4:5 say 4x:5x.
  They decided to buy a gift for their sister, sharing to
  cost in the ratio 3:4 say 3y:4y.
  B is left with 145 means 5x-4y=145.
  A is 4x/3=3Y
  Y=4X/9
  5X-4(4X/90)=145
  X=45,Y=20 3Y+4y=GIFT TOTAL MONEY=60+80=140

• let the amounts be 4x:5x;
  share of cost = 3y:4y;
  then 2/3(4x)=3y and 5x-4y=145;
  on solving the equations we get the value of gift as 447.09
