Gate DA 2025 | Question - 10 | General Aptitude

We are given:

Dr. Gita’s earnings per shift is ₹1000 . (X-0.2), where X is the number of patients in that shift.

Step 1: Extract Data from the Bar Chart

Step 2: Compute Total Earnings

We calculate earnings for each shift group:

$$\text{Earnings per shift} = 1000 \cdot (X - 0.2)$$

Now multiply by the number of shifts:

• For $X = 5$:
  $\text{Earnings} = 1000(5 - 0.2) = 1000 \cdot 4.8 = ₹4800$
  Total: $20 \cdot 4800 = ₹96,000$

• For $X = 6$:
  $1000(6 - 0.2) = ₹5800$
  Total: $40 \cdot 5800 = ₹232,000$

• For $X = 7$:
  $1000(7 - 0.2) = ₹6800$
  Total: $30 \cdot 6800 = ₹204,000$

• For $X = 8$:
  $1000(8 - 0.2) = ₹7800$
  Total: $10 \cdot 7800 = ₹78,000$

Step 3: Compute Total and Average

Total Earnings:

$$96,000 + 232,000 + 204,000 + 78,000 = ₹610,000$$

Average per shift (over 100 shifts):

$\frac{610000}{100}=\mathbf{\text{₹6,100}}$
