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

- 19^2 + (1024)^1/2 – 256 – 9*7 = ?
8072749266Option C

19^2 + (1024)^1/2 – 256 – 9*7 = ?

=>361 + 32 – 256 – 63 = ?

=>? = 74 - 9^3 -23^2 – 14^2 = ?
57648Option D

9^3 -23^2 – 14^2 = ?

=>729 – 529 – 196 = ?

=>? = 4 - (440.89)^1/2 + (169.13)^1/2 – 14^2 + 207.88 = ?
3346384248Option B

(440.89)^1/2 + (169.13)^1/2 – 14^2 + 207.88 = ?

=>(441)^1/2 + (169)^1/2 – 14^2 + 208 = ?

=>21 + 13 – 196 + 208 = ?

=>? = 46 - 44.97 + 310.08 + 9.13*4.89 = ?^2
1715162012Option D

44.97 + 310.08 + 9.13*4.89 = ?^2

=>45 + 310 + 9*5 = ?^2

=>?^2 = 400

=>? = 20 - 54.97% of 800 + 32.89*4 – 396.12 /17.91 = ?
500495550476485Option C

54.97% of 800 + 32.89*4 – 396.12 /17.91 = ?

=>55% of 800 + 33*4 – 396/18 = ?

=>440 + 132 – 22 = ?

=>? = 550 - Speed of boat A and boat B in still water is 42 km/hr. and 48 km/hr. resp. and speed of stream is 4 km/hr. If both boats are travelling towards each other and meet after 7 hours. What will be maximum distance between both boats?
700 km742 km717 km600 km630 kmOption E

If boat A travelling against upstream and boat B travelling with the stream

Distance = 38*7+52*7 = 630 km - Mr.Bean earn Rs.42000 in a month. He spends 20% in house rent and 60% of rest in others. Find the saving of him.
Rs.16260Rs.15250Rs.16520Rs.13440Rs.11450Option D

Amount spent on house rent = 0.2*42000

= Rs.8400

Remaining amount = 42000- 8000 = Rs.33600

Other spending = 0.6*33600 = Rs.20160

Savings = 33600 – 20160 = Rs.13440 - The ratio of cost price and marked price of an article is 20:27 resp. If profit earned and discount given is Rs.192 and Rs.648 resp. Find the profit percentage.
8%14%12%10%9%Option A

Let the CP and MP be Rs.20x and Rs.27x resp.

20x+192 = 27x – 648

=>x = 120

CP of the article =20*120 = Rs.2400

Profit% = 192/2400*100 = 8% - Average weight of 26 content developers is 62 kg. If weight of one more content manager is included. The average weight increased by 1 kg. Find the weight of the newly added content manager.
94 kg78 kg95 kg89 kg80 kgOption D

Weight of newly added content manager = 63*27 – 62*26

= 89 kg - A cylindrical tank is filled in 16 minutes if the water is flowing at the rate of 144 m^3 per minute. Area of the base of cylinder is 192 m^2. If the certain quantity of the water is taken out of the tank 1344 m^3 water is left in the tank. Find decrease in the level of water.
14 m10 m6 m8 m5 mOption E

Volume of tank = 144*16 = 2304 m^3

Height = 2304/192 = 12 m

Height = 1344/192 = 7 m

Decrease in the level of water = 12-7 = 5 m
