Question

21) Viji and Ajith are neighbours. They sold their plots of land together and divided the amount in the ratio 4:6. Ajith got Rs. 4000 more than Viji in the deal. How much money did each get?

​

Answer 1

• Ajith got (6/10-4/10) part of the total more than viji.
• I.e., Ajith got 2/10 part of total
• Given that it is 4000
• Total amount×2/10=4000
• Therefore total amount=4000÷2/10=4000×10/2=20000
• Viji's share=4/10×20000=8000
• Ajith's share=6/10×20000=12000
