Weight of Ayush and Abhishek are in the ratio of 8 : 5. Abhishek's weight increases by 40 percent and total weight of Ayush and Abhishek both increases by 60 percent. If total weight becomes 104 kg, then what is the weight of Ayush after the increment ?

69 kg 

                     Ayush  :  Abhishek  : Ayush + Abhishek 

Original             8      :        5       :          13                         

New                                5x\(\frac{140}{100}\)  :     13x\(\frac{160}{100}\)

                                       35       :            104

Total weight of Ayush and Abhishek = 104 kg(given)

Thus, R = 1 

Thus, increased weight of Abhishek = 35 

Increased weight of Ayush = 104 - 35 = 69 kg
