A sum of money fetches Rs. 480 as simple interest at the rate of 10% per annum after 12 years What is the sum?

250

200

350

400

500

Option D Principal = SI * 100 / T* R = 480 *100/ 10*12 = Rs. 400

The simple interest is occured on an amount of Rs. 40,000 at the end of 3 years isRs. 14,400. What would be the compound interest accured on the same amount at the same rate in the same period?

Option D subract 15, 30…. from the appropriate term.

7, 10, 16, 28, 52, ?, 196

Option A Add 3, 6 ,12….

Two taps A and B can deliver water to a drum at the rate of 4 lit/min and 6 lit/min respectectively. If capacity of drum is 2400 li then what part of drum will remain empty after one hour of starting of both taps?

1/2

3/4

2/3

1/5

1/4

Option B Total water delivered to the dam in one hour =(4+6)x60(1 hr=60 min) =600 liters Filled part of dam =600/2400=1/4 Empty part of dam=1-1/4=3/4

Three pipes A,B and C can fill a cistern in 12 hr. 16 hr and 20 hr. respectively. all the pipes are opened together and after working two hours pipes B and c are closed. Find time taken by pipe A to fill the remaining part of cistern.

Option A capacity of tank=L.C.M of (12,16,20)=240unit/hr. Efficiency of pipe A =240/12=20 unit/hr. Efficiency of pipe B =240/16=15 units/hr. Efficiency of pipe C =240/20=12 unit/hr. Let pipe A taken x hour to fill the remaning part 20(x +2)+15 x 2 + 12x 2=240 =20x + 40+30+24=240 =20x=146 =x=7.3hrs

Sai can type 180 pages in two hours while raj can type 240 pages in one and half hour. if total pages earned by them is Rs.3100.then what is the share of Sai?

1120

2245

1678

1116

1453

Option D Ratio of efficiencies of Sai and Raj =180/2:240/3/2 =9:16 share of Sai=9/25 x3100=Rs=1116

30 workers working 7 hours a day can finish a piece of work in 18 days. if the laborers work 6 hours a day. Then What is the number of workers required to finish the same piece of work in 30 days?

10

21

Option E Required numper of Laborers =30x7x18/6×30=21

Hey! This is kind of off topic but I need some help from an established
blog. Is it difficult to set up your own blog?
I’m not very techincal but I can figure things out pretty
quick. I’m thinking about setting up my own but I’m not sure where to begin. Do you
have any points or suggestions? Appreciate it
