- If Pipes A and B can fill a tank in 15 min and 20 mins respectively and pipe C empties the tank in 12 mins. what will be the time taken by A, B and C together to fill the tank completely?
50 minutes40 minutes20 minutes30 minutes10 minutesOption D

LCM = 60 = (+4+3-5) = 2

Tank filled in 1 min = 2 units

Total time = 60/2 = 30 minutes - If ratio of ages of P and Q before 4 year ago is 5 : 4 and after 12 years sum of their ages will be 68 years, their what was Pâ€™s age 2 years ago ?
29 years26 years24 years22 years21 yearsOption D

Age increased in 16 year = 32 years

Sum of Age of P and Q before 4 years = 36

5x + 4x = 36

X = 4

Pâ€™s age 2 years ago = 5x + 2 = 22 years - If A invested Rs. 12000 at some rate of interest of S.I and B joined him after 3 months investing 16000 at same rate of interest if A leaves before 2 month of completion, then what will be the share of Bâ€™s profit after 1 year if total profit is Rs. 22000?
Rs.17000Rs.12000Rs.10000Rs.19000Rs.16000Option B

Ratio= 5:6

Bâ€™s share = 22000 Ã— 6/11 = Rs.12000 - If a boat travels 18 km more in downstream than in upstream in 3 hr. and if the speed of the Boat in still water is 20 km/hr. find the distance travelled by boat in downstream in 4 hr. ?
92 km98 km96 km88 km90 kmOption A

(Ds â€“Du ) 3 = 18 km

Different in 1 hr. = 6km

Ds and Du

Speed of boat in still water = 20 km/hr.

Ds = 23 km/hr.

Du = 17 km/hr. Distance travelled = 4 Ã— 23 = 92 km - When a person sold an article, his profit percent is 60% of the selling price. If the cost price is increased by 75% and the selling price remains the same, then find decrement in the profit is what percent of the selling price of the article?
50%40%30%10%20%Option C

Let the selling price be 250x

Then, profit = 150x

CP=250x âˆ’ 150x = 100x

Now, new C.P. = 100x Ã— 175/100 = 175x

New S.P. = 250x

New profit = 250x â€“ 175x = 75x

Required % = (150xâˆ’75x)/250x Ã— 100 = 30% - 130, 154, 186 , ? , 274, 330
