**Directions(1-5):** What will come in place of question mark “?” in the following questions.

- [559/13 + 19*7] – 819 / 21 of 3 = ?
150125163144174Option C

[559/13 + 19*7] – 819 / 21 of 3 = ?

=> ( 43 + 133 ) – 819 / 63 = ?

=> 176 – 13 = ?

=> ? = 163 - {[36*23 + 442 / 17] + [18* 25 – ?] – 209 } = 778
350285299310317Option E

{[36*23 + 442 / 17] + [18* 25 – ?] – 209 } = 778

=> ( 828 + 26 ) + (450 – ?) – 209 = 778

=> 1095 – ? = 778

=> 1095 – 778 = ?

=> ? = 317 - {[42% of 550 + 16] – 12 * (244 / 4 – 54)} = ?
163105111125150Option A

{[42% of 550 + 16] – 12 * (244 / 4 – 54)} = ?

=>{ (231 +16) – 12*(61-54)} = ?

=> (247 – 12*7) = ?

=> ? = 163 - [613 – {(64 + 37*16) – 501} * (946 / 86 – ?)] = 148
188121016Option B

[613 – {(64 + 37*16) – 501} * (946 / 86 – ?)] = 148

=> [613 – (656 – 501)* (11- ?) ] = 148

=> 613 – 155*(11 – ?) = 148

=> ? = 8 - (35% of 40% of 650 – 62) + ? * (592 / 16 – 26) = 315
1022153026Option E

(35% of 40% of 650 – 62) + ? * (592 / 16 – 26) = 315

=> (35% of 260 – 62) + ? *(37 – 26) = 315

=> (91 – 62) + ?*11 = 315

=> ? = 26 - If books bought at prices ranging from Rs. 200 to Rs. 350 are sold at prices ranging from Rs. 300 to Rs. 425, what is the greatest possible profit that might be made in selling eight books ?
Rs. 1450Rs. 1520Rs. 1250Rs. 1000Rs. 1800Option E

Least Cost Price = Rs. (200 * 8) = Rs. 1600.

Greatest Selling Price = Rs. (425 * 8) = Rs. 3400

Required profit = Rs. (3400 – 1600) = Rs. 1800. - The speed of a car increases by 2 kms after every one hour. If the distance travelling in the first one hour was 35 kms. what was the total distance travelled in 12 hours?
552 kms488 kms450 kms352 kms500 kmsOption A

Total distance travelled in 12 hours

= (35+37+39+…..upto 12 terms)

This is an A.P with first term, a=35, number of terms, n= 12,d=2.

Required distance = 12/2[2 x 35+{12-1) x 2] = 6(70+23) = 552 kms. - A train of length 110 meter is running at a speed of 60 kmph. In what time, it will pass a man who is running at 6 kmph in the direction opposite to that in which the train is going?
76524Option B

Distance = 110 m

Relative speed = 60 + 6 = 66 kmph (Since both the train and the man are in moving in opposite direction)

= (66*5/18) m/sec = 55/3 m/sec

Time taken to pass the man = (100*3/55) = 6 s - Sobha’s father was 38 years of age when she was born while her mother was 36 years old when her brother four years younger to her was born. What is the difference between the ages of her parents?
12810614Option D

Let Sobha’s age =x and her brother’s age =x−4

Sobha’s father’s age =x+38

Sobha’s mother’s age =(x−4)+36=x+32

Sobha’s father’s age – Sobha’s mother’s age

= (x+38)−(x+32)

= 6 - Three pipes A, B and C can fill a tank from empty to full in 30 minutes, 20 minutes, and 10 minutes respectively. When the tank is empty, all the three pipes are opened. A, B and C discharge chemical solutions P,Q and R respectively. What is the proportion of the solution R in the liquid in the tank after 3 minutes?
7/116/136/115/113/10Option C

Ratio of water filled by A,B,C per minute = 1/30:1/20:1/10 = 2:3:6

Proportion of R any time = 6/(2+3+6) = 6/11

I?ve been exploring for a little for any high-quality articles or blog posts on this sort of area . Exploring in Yahoo I at last stumbled upon this site. Reading this info So i?m happy to convey that I’ve a very good uncanny feeling I discovered just what I needed.
