Question

The daily wages of Ramu, Raju and Rajesh are in the ratio of 2 : 3 : 4. If their salaries are increased by 20%, 30% and 15% respectively then Raju's salary will be increased by Rs.120. What was the salary of Ramu initially?

Answer 1

let Ramu's salary be 2x
Raju's salary be 3x
Rajesh's salary be 4x
Raju's salary increase by =3x*(30/100)
=9x/10
then
9x/10=120
or x=1200/9
or x=133.33
then Ramu's salary was
=2*133.33=266.66.....(ans)

Answer 2

Answer:

Rs.399.99

Step-by-step explanation:

Given :The daily wages of Ramu, Raju and Rajesh are in the ratio of 2 : 3 : 4.

To Find : If their salaries are increased by 20%, 30% and 15% respectively then Raju's salary will be increased by Rs.120. What was the salary of Ramu initially?

Solution:

The daily wages of Ramu, Raju and Rajesh are in the ratio of 2 : 3 : 4.

Let the ratio be x

So, Ramu's wage = 2x

Raju's wage = 3x

Rajesh's wage = 4x

Their salaries are increased by 20%, 30% and 15% respectively

Raju's increase in salary = $30\% \times 3x$

                                        = $\frac{30}{100}\times 3x$

                                        = $0.9x$

We are also given that Raju's salary will be increased by Rs.120

So,  $0.9x = 120$

$x = 133.33$

Raju's salary initially = 3x = $3 \times 133.33 =399.99$

Hence The salary of Ramu initially was Rs.399.99
