3 mangoes and 4 apple cos rs 85.5 apple and 6 peech cost rs 122. 6 mango nd 2 peech cost rs 114. find cost of combine prize of 1mango 1 apple nd 1 peech

• let mangoes be x
  let apples be y
  let peech be z
  3x+4y=85
  5y+6z=122
  6x+2z=114
  while solving we will get x=15,y=10,z=12
  cost of combine prize of 1mango 1 apple nd 1 peech=x+y+z=37

  let m=per mango's price a= per apple's price and p= per peech's price
  now 3m+4a=85
  5a+6p=122
  and 6m+2p=114
  now solving this 3 equation we get m=15,a=10,p=12

• 3m + 4a = 85 ..(1)
  5a + 6p = 122 ..(2)
  6m + 2p = 144 ..(3)
  (1) x 2 => 6m + 8a = 170
  4 x (3) => 6m + 2p = 144
  Solving we get 8a - 2p = 56 ..(4)
  
  (2) => 5a + 6p = 122
  3 x (4) = 24a - 6p = 168
  Solving we get a = 10, p = 12, m = 15
  So a + p + m = 37
