**Directions(1-5):** What approximate value will come in place of question mark ‘?’ in the following questions.

- 16.12*15.94 + 654.92 – 344.83 = ?*5.95
8884908095Option C

16.12*15.94 + 654.92 – 344.83 = ?*5.95

=>16*16 + 655 – 345 = ?*6

=>256 +655 – 345 = ?*6

=>911 – 345 = ?*6

=>566/6 =?

=>? = 90 - 35.1% of 1599 = ? – (449.96/6.12)*2
620655750815710Option E

35.1% of 1599 = ? – (449.96/6.12)*2

=>35% of 1600 = ? – (450/6)*2

=>560 = ? – 75*2

=>560 = ? – 150

=>? = 710 - 30.11*(1025)^1/2 + 196 = ?^2 – 287
4038253048Option B

30.11*(1025)^1/2 + 196 = ?^2 – 287

=>30*(1024)^1/2 + 196 = ?^2 – 287

=>30*32 + 196 = ?^2 – 287

=>960 + 196 + 287 = ?^2

=>?^2 = 1444

=>? = 38 - 18.003*3.99 *(135.003 / 26.97) – ( 15.001*3.94) = ?
289250300350324Option C

18.003*3.99 *(135.003 / 26.97) – ( 15.001*3.94) = ?

=>18*4*(135/27)- (15*4) = ?

=>72*5 – 60 = ?

=>? = 360 – 60

=>? = 300 - 41.97 *5.12/2.99 + 49.89 = ?*1.99
5545405260Option E

41.97 *5.12/2.99 + 49.89 = ?*1.99

=>42*5 /3 + 50 = ?*2

=>70 + 50 = ?*2

=>? = 60 - A pipe can fill a cistern in 8 hours. After half the tank is filled, three more similar taps are opened. What is the total time taken to fill the cistern completely?
64589Option C

Part filled by P and Q = In One hour pipe can fill = 1/8

Time is taken to fill half of the tank = 1/2 * 8 = 4 hours

Part filled by four pipes in one hour = (4*1/8) = 1/2

Required Remaining Part = 1/2

Total time = 4 + 1 = 5 hours - Dhipan borrowed Rs.800 at 6% per annum and Shahrukh borrowed Rs.600 @ 10% per annum. After how much time, will they both have equal debts?
50/342/351/247/353/3Option A

800+(800*6*T)/100 = 600+(600*10*T)/100

T=50/3 yr. - The perimeter of a rectangular ppalyground is 210 m. Find the cost of gardening 2 m broad boundary around rectangular playground whose perimeter The cost of gardening is Rs 14 per m2.
52106200610460005480Option C

Given 2(l+b) = 210

2 m broad boundary means increase in l and b by 4 m

So area of the boundary will be [(l+4)(b+4) – lb] = 4(l+b) + 16 = 2*[2(l+b)] + 16 = 2*210 + 16 = 436 m2

So cost of gardening = 436*14 = Rs. 6104 - One type of liquid contains 20 percent of milk and second type of liquid contains 40 percent milk. If 4 part of the first and 6 part of the second are mix, then what is the percent of water in the mixture.
74%70%68%60%50%Option C

Let water = 80ltr and 60ltr in first and second mixture respectively

Percent of water = [(80*4 + 60*6)/1000]100 = 68% - A urn contains 4 red balls, 5 green balls and 6 white balls, if one ball is drawn at random, find the probability that it is neither red nor white.
