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

- 175% of 460 + 110% of 170 + 2^? = 100
54837Option D

175% of 460 + 110% of 170 + 2^? = 100

=>2^? = 1000 − 805 − 187 = 8

=> ? = 3 - 3.2% of 500 × 2.4% of ? = 288
700750800745820Option B

3.2% of 500 × 2.4% of ? = 288

=> 16*2.4/100 * x = 288

=> x = 750 - 16.5% of 300 + 70.5% of 1400 – 10% of 480 = ?
9891000950900990Option A

16.5% of 300 + 70.5% of 1400 – 10% of 480 = ?

=>49.5 + 987 – 48 = ?

=> ? = 989 - 564.97 + 82.00 × 44.8 – 34.2 = ?
48505100450050504220Option E

564.97 + 82.00 × 44.8 – 34.2 = ?

=> ? = 565 + 82 × 45 – 34 == 4220 - (4444 ÷ 40) + (645 ÷ 25) + (3991 ÷ 26) = ?
270290325274310Option B

(4444 ÷ 40) + (645 ÷ 25) + (3991 ÷ 26) = ?

=>(4444 ÷ 40) + (645 ÷ 25) + (3991 ÷ 26) = ?

= 111.1 + 25.8 + 153.5 == 290 - Mathews gave a loan of Rs. 1200 to Antony and recovered it at the rate of Rs. 180 each month for eight months, commencing from the end of 1st month. What is the effective rate of simple interest per annum?
60%20%50%30%40%Option D

Principal = Rs.1200

Amount = Rs. 180 x 8 = Rs. 1440

Interest = Rs 1440 – Rs 1200 = Rs. 240

Time = 8 months = 8/12 years

=>240 = [1200 × 2 × r]/[ 3 × 100] =>r = [3 × 100 × 240]/[ 1200 × 2] = 30% - The work done by a woman in 8 hours is equal to the work done by a man in 6 hours and by a boy in 12 hours. If working 6 hours per day 9 men can complete a work in 6 days then in how many days can 12 men, 12 women and 12 boys together finish the same work working 8 hours per day?
1(3/4) day2(5/2) day1(2/3) day2(5/4) day1(1/2) dayOption E

8 Women = 6 Men = 12 Boys

12M + 12W + 12B = 12M + 9M + 6M = 27M

Now, 9 × 6 × 6 = 27 × 8 × D2

=> D2 = (9 × 6 × 6)/(27 × 8) = 1(1/2) day - A 180-metre long train crosses another 270-meter long train running in the opposite direction in 10.8 seconds. If the speed of the first train is 60 kmph, what is the speed of the second train in kmph?
105 kmph80 kmph90 kmph100 kmph70 kmphOption C

Time taken = 60 kmph = 60×5/18 = 50/3 m/sec.

Let the speed of other trains be x m/sec.

=> 10.8 = [180 + 270]/ 50/3 + x

=> 180 + 10.8x = 450

=> 10.8x = 450 − 180 = 270

=> x = 270/10.8 = 25 metre/sec.

= 25 × 18/5 kmph = 90 kmph - The Average age of 12 men is decreased by one year when two of them having ages 28 years and 32 years are replaced by two women of same age . Find the age of a women.
24 years20 years23 years26 years30 yearsOption A

Age of each women be y and average age of 12 men be x.

Now,

[12x-28-32+2y]/12 = x-1

=> y = 24 - A boy picks two cards from a pack of 52 well shuffled – cards without replacement. Find the probability that the cards are even numbered spades.
