APTITUDE:

Q1. The average age of a class of 35 students is 15 years. If the teacher's age is also included the average age increases by one year. Furthermore, if the average age of the teacher's family having a wife and a son is 40 years and the son's age is 80% less than his mother's age, then the age of the teacher's wife is

a) 57.5 years
b) 50 years
c) 47.5 years
d) 55.5 years

ANS: a

Explanation:

The total age of 35 students = 35 * 15 = 525
By including teacher's age, average increases by one.
So the total age of 35 students and one teacher = 36 * 16 = 576
Hence we have (w + s + 51) / 3 ................ (i)
Also s = w - ( 80w/100 ) = w/5
Hence from equation (i), we have
[ w + (w/5) + 51 ] / 3 = 40
=> 6w/5 = 69
=> w = 57.5 years
Hence The age of teacher's wife is 57.5 yrs

Q2. A cloth merchant on selling 33 metres of cloth obtains a profit equal to the selling price of 11 metres of cloth. The profit is

a) 40 %
b) 22 %
c) 50 %
d) 11 %

ANS: c

Explanation:

SP of 33 metres of cloth = CP of 33 metres + S.P of 11 meters
So, SP of 22 metres of cloth = CP of 33 metres= CP of 22 metres + CP of 11 metres
It means by selling 22 metres of cloth the merchant covers the cost price of 22 metres along with cost price of 11 metres.
Gain = ( 11/22 ) * 100 = 50%.
So, Ans is option C.

Q3. A, B and C started a business with their investments in the ratio 1: 2: 4. After 6 months A increased his capital by 50% and B invested twice the amount as before, while C withdrew 1/4th of his own investment. The ratio of their profits at the end of the year was

a) 10: 5: 9
b) 5: 12: 14
c) 6: 9: 17
d) 5: 14: 16

ANS: b

Explanation:

Let their investments be Rs 100, Rs. 200 and Rs. 400.
Now, ratio of profits = I1 T1 : I2 T2 : I3 T3
Where I stands for Investment and T stands for Time

Q4. Three men can complete a piece of work in 6 days. Two days after they started the work, 3 more men joined them. How many days will they take to complete the remaining work?

a) 1 day
b) 2 days
c) 3 days
d) 4 days

ANS: b

Explanation:

Q5. If a, b are rationals and a√2 + b√3 = √98 + √108 - √48 - √72, then the values of a, b are respectively

a) 1, 2
b) 1, 3
c) 2, 1
d) 2, 3

ANS: a

Explanation:

a√2 + b√3 = √98 + √108 - √48 - √72
a√2 + b√3 = 7√2 + 6√3 - 4√3 - 6√2
a√2 + b√3 = 1√2 + 2√3
On comparing the coefficients, we get
a = 1, b = 2.

Q6. A shopkeeper sells an article at 15% gain. Had he sold it for Rs. 18 more, he would have gained 18%. The cost price (in Rs.) of the article is

a) 540
b) 318
c) 600
d) 350

ANS: c

Explanation:

Let CP be Rs. 100
Now, gain = 15%
S.P = Rs. 115
Now, for 185% gain, SP = Rs.118
Difference between two SP is Rs. 3
Now, CP = 100
Difference of SPs = Rs. 3
If difference is Rs. 18 (Given), the by unitary approach, CP = Rs. 18 / ( 3 *100 ) = Rs. 600
So, Ans. is option C

Q7. The ratio of boys and girls in a college is 5: 3. If 50 boys leave the college and 50 girls join the college, the ratio becomes 9: 7. The number of boys in the college is

a) 300
b) 400
c) 500
d) 600

ANS: c

Explanation:

The ratio of boys and girls in a college is 5: 3.
Let the boys in college = 5x
Let the girls in college = 3x
(5x -50) / (3x + 50) = 9 / 7
35x - 350 = 27x +450
8x = 800
x = 100
Hence, the number of boys in the college = 5x = 500
So, Ans is option C

Q8. If the amount is 338 times the sum after 3 years at compound interest compounded annually, then the rate of interest per annum is

a) 25%
b) 50%
c) 1623%
d) 3313%

ANS: b

Explanation:

If the amount becomes 3 3/8 times of the principal
i.e means it becomes = 27 /8 times of P
Also Given that A = P ( 1 + r /100 ) t
r = rate % , t = 3years
27/8 P = P ( 1 + r /100 ) 3
27/8 = ( 1 + r /100 ) 3
3/2 = 1 + r/100
r = 50%
Hence, the answer is option B.

Q9. Two trains 180 metres and 120 metres in length are running towards each other on parallel tracks, one at the rate 65 km/hour and another at 55 km/hour. In how many seconds will they be clear of each other from the moment they meet?

a) 6
b) 9
c) 12
d) 15

ANS: b

Explanation:

Total distance = 180 + 120 = 300 m
Relative speed = 65 + 55 = 120 km/hr
= 120 × 1000/3600 m/sec
Therefore, time = distance/speed = 300/120 × 3600/1000 = 9 sec
So, Ans. is option B

Q10. A single discount equivalent to successive discounts of 20%, 10% and 5% is

a) 35 %
b) 35.6 %
c) 31.6 %
d) 36.1 %

ANS: c

Explanation:

Let Cost price = Rs.100
After 1st discount of 20% C.P. = 100 - 20 = 80
Similarly after 2nd Discount of 10% Cost Price = 80 - (10/100 × 80) = 72
Now, After a discount of 5% , C.P. = 72 - (5/100 × 72) = 72 - 3.6 = 68.4
Therefore, net discount = 100-68.4 = 31.6
Ans Is option C
