Bar chart: profits over 5 years average to ₹40 cr; if 4 years have profits 30, 35, 50, 45 cr, the 5th year's profit is:
A₹30 cr
B₹35 cr
C₹40 cr
D₹45 cr
Answer & Solution
Correct answer: C. ₹40 cr
1. Total over 5 years = 40 × 5 = 200 cr.
2. Sum of 4 known years = 30 + 35 + 50 + 45 = 160.
3. 5th year = 200 − 160 = ₹40 cr.
