Answer 2

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 %

b)15 % gain
