Direction (Q.11-15): In each of the
number series questions, one number is wrong. You have to identify
Quantity
sold in quintals that number and assuming that a
Price in new series starts with that number,
following the same logic as in the
Rs.Per kg
given series. Which of the numbers
given in (1), (2), (3), (4) and (5)
below each series will be the third
number in the new series?

18. Let the average expenditure of the boarder
be Rs.x
∴ ⎯ + ⎯ = 1 (full cistern)
total expenditure = Rs.30x
After 10 boarders joined,
Average expenditure = Rs. (x-5)
Total expenditure = 40(x-5)
∴ 40 (x-5) - 30x = 1300
⇒ x = Rs.150
∴ Original monthly expenditure
= 30 × Rs.150
= Rs.4500
