A fruit seller sells only soursops and avocados. The ratio of soursops to avocados is 5:4. A total of 68 fruits are added. The number of soursops becomes 2 times as many as before and the number of avocados becomes 4 times as many as before. How many fruits are there in the end?
soursops --- 5x
avocados -- 4x
total = 9x
after adding 68 , total is 9x + 68
in new mix, sourdrops = 10x
in new mix, avoc. = 16x
9x + 68 = 10x + 16x
68 = 17x
x = 4
at start:
sourdrops --- 20
avods ----- 16
total = 36
after addition:
sourdrops = 40
avocs = 64
new total = 104
how many were added? 104-36 = 68
I have the correct answer.
