Suresh earns 35%, 50% on the first two investments but loses 25% on the third, if the ratio of the three investments is 3: 4: 5. What is the overall gain or loss on the neem taken together?
Answers
Answer:
15%
Step-by-step explanation:
let the total amount invested be x
hence first invested amount be 3x
similarly second and third investment should be 4x and 5x
given that he earns 35% in first investment
i.e 3x + (3x*35/100)
and in second investment he earned is
4x + (4x*50/100)
and in third investment he loses 25%
i.e (-5x*25/100)
therefore total amount earned will be
= 105x/100 + 200x/100 - 125x/100
= 180x/100
= 9x/5
therefore gain percentage will be
= (9x/5)*100/ 12x
= 9x * 100 / 5*12x
= 900/60
= 15%
hence he is overall gain is 15%
Given : ratio of the three investments is 3: 4: 5
Suresh earns 35%, 50% on the first two investments but loses 25% on the third,
To Find : overall gain or loss
Solution:
ratio of the three investments is 3: 4: 5
Hence let say three investments are 300x , 400x and 500x
Total = (300x + 400x + 500x) = 1200x
Earn on 1st = (35/100)300x = 105x
Earn on 2nd = (50/100) 400x = 200x
Loos on 3rd = (25/100)500x = 125x Hence Earns = - 125x
Total Gain = 105x + 200x - 125x
= 180x
overall gain % = (180x/1200x) * 100
= 15 %
