    Solution

    ATQ, We can say that the income of S be Rs. тАШxтАЩ So, income of Q = (x + x) ├Ч (4000/100) = Rs. тАШ41xтАЩ Let the expenses of 'S' be тАШ12yтАЩ So, expenses of Q = 12y ├Ч (125/12) = Rs. тАШ125yтАЩ ATQ; 125y тАУ 12y = 90,400 Or, 113y = 90400 So, y = 800 So, 41x тАУ 800 ├Ч 125 = 3,89,600 + x тАУ (12 ├Ч 800) Or, 40x = 3,89,600 + 100000 тАУ 9600 Or, 40x = 480000 So, x = 12000 So, income of S = Rs. 12,000
