A truck is carrying grapefruit juice, passionfruit juice and peach juice bottles in a ratio of 1 : 2 : 4. If there are 1139 peach juice bottles then how many bottles in total are there?



Answer :

There is a few approach to find the result. We can add 1 + 2 +4=7 and make proportion
4  ------------------- 1139      (4 units in our ratio  these are peach jouice bottles)
7 --------------------x            (sum of unit in the ratio its x bottles)
crossmultiply
4x=7*1139
4x=7973     /:4
x=1993.25
There are 1993 botttls.
