Six persons went to a hotel to have their meals. Five of them spent ₹30 each on their meals. The sixth person spent ₹50 more than the average expenditure of all the six. What was the total money spent by all the persons?

A₹270

B₹240

C₹300

D₹264

Answer:

B. ₹240

Read Explanation:

Let the total expenditure be (T).

Given

  • 5 persons spent: (5 \times 30 = 150)

  • Let the 6th person spent = (x)

So,

T=150+xT = 150 + x
Average expenditure


Average=T6\text{Average} = \frac{T}{6}

Given:

x=T6+50x = \frac{T}{6} + 50

Substitute (T)

x=150+x6+50x = \frac{150 + x}{6} + 50

Multiply both sides by 6:

6x=150+x+3006x = 150 + x + 300

6x=450+x6x = 450 + x

5x=450x=905x = 450 \Rightarrow x = 90
Total expenditure

T=150+90=240T = 150 + 90 = 240
Final Answer: ₹240
