Pipe P can drain the liquid from a tank in 4/4 the time that it takes pipe Q to drain it and in 2/3 the time that it takes pipe R to do it.

Certain stocks in January were 10% less than they were in February and 20% greater than they were in March. What was the percentage decrease in the stocks from February to March? | [
"25%",
"5%",

"20%"
] | A | Let J,F,M be the values of the stock in Jan,Feb and March.
Thus, per the question, J = 0.9F = 1.2M ----> M =0.75F
Thus the % decrease from F to M = (F-M)/(F) *100 = (F-0.75F)/F * 100 = 0.25*100 = 25 %, D is the correct answer. | AquaRat_train |

Find the cost of carpeting a room 13 m long and 9 m broad with a carpet 75 cm wide at the rate of Rs.12 per square metre. | [
"1888",
"1854",
"1999",
"1872"
] | D | Explanation:
Area of the carpet = Area of the room = (13 × 9) m2 = 117 m2.
Length of the carpet = (area/width) = 117 ×(4/3) m = 156 m.
Therefore Cost of carpeting = (156 × 12) = Rs.1872
