Correct Answer - Option 3 : Rs. 80,598
Given:
Investment of Priti and Shobha respectively = Rs. 12,240 and Rs. 20,400
Shobha left after 7 months
Investment of Tina after she joined = Rs. 4080 + Shobha's investment
Profit share of Tina = Rs. 23,940
Concept used:
As we know, Profit is directly proportional to (Investment × Time)
Calculation:
Investment of Tina = Rs. (4080 + 20,400) = Rs. 24,480
Ratio of the profit share of Priti, Shobha and Tina = 12240 × 12 : 20400 × 7 : 24480 × 5
⇒ 36 : 35 : 30
So, 30 = Rs. 23,940
Then, 101 = Rs. (23,940/30) × 101
⇒ Rs. 80,598
∴ Total profit of the year was Rs. 80,598
