After two years her sister Rama joined her with an amount of Rs. $85,000$.Therefore,Rama did not invest any additional amount. On completion of $4$ years from the opening of workshop they earned an amount of Rs. $1,95,000$. What will be Radhika's share in the earning ?

Answer 1

Radhika's Investment for $4$ years $=40,000+50,000+.60,000+70,000=2,20,000$ Rs

Rama's Investment for $2$ years $=85000\times 2=170000$ Rs.

Ratio of their investment$=22:17$

Total earngings $=1,95,000$ Rs.

Radhika's share $=\frac{22}{39}\times 195000=1,10,000$ Rs.
