Question

Vinod's and javed's salaries are in the proportion of 4 : 3 respectively. What is vinod's salary? (i) javed's salary is 75% that of vinod's salary. (ii) javed's salary is rs. 4500.

Answer 1

Vinod = 4x
Javed = 3x

(i)
$4x \times \frac{75}{100} = 3x$

(ii)
$4x \times \frac{75}{100} = 4500 \\ x = 4500 \times \frac{100}{75} \times \frac{1}{4} \\ x = 1500$

Vinod = 1500*4 = 6000
Javed = 1500*3 = 4500
