Question 179

The number of employees in companies A, B and C are in a ratio of 3 : 2 : 4 respectively. If the number of employees in the three companies is increased by 20%, 30% and 15% respectively, what will be the new ratio of employees working in companies A, B and C respectively ?

Solution

Let the no. of employees in companies A, B and C in respectively be $$3x , 2x$$ and $$4x$$

After respective increase in the number of employees :

A = $$\frac{120}{100} \times 3x = 3.6x$$

B = $$\frac{130}{100} \times 2x = 2.6x$$

C = $$\frac{115}{100} \times 4x = 4.6x$$

=> Required ratio = 3.6 : 2.6 : 4.6

= 18 : 13 : 23
