1.In a triangle PQR the internal bisector of ∠PQR= 76° and external bisector of other base angles meet at point O. Then find the ∠QOR=?
A. 38°
B. 19°
C. 42°
D. 57°
Solutions
∠PRY = ∠P + ∠Q
½ ∠PRY = ½ ∠P + ½ ∠Q
∠ORY = 38° + ∠OQR —– (1)
In Triangle QOR
∠ORY = ∠OQR + ∠QOR —- (2)
From (1) and (2)
38° + ∠OQR= ∠OQR + ∠QOR
∠QOR = 38°
2. A train travels a certain distance without stoppages at an average speed of 84 km/hr and with stoppages it covers the same distance at an average speed of 58 km/hr. How many minutes per hour does it stop?
A. 10 min
B. 20 min
C. 30 min
D. 25 min
Solutions
Stoppage time/hour = Change in speed/ Faster Speed
Due to stoppage it cover (84 – 56) = 28 km less per hour
So for travelling 28 km time taken = 28/84 hr
= 2/ 6 hr = 1/3 hr = 1/3 x 60 =20 min
3. A Railways employee’s pension on retirement from service is equal to half the average salary during last 36 months of his service. His salary from 1 January, 2013 is Rs. 4600 per month with increment of Rs. 200 on 1 November 2013, 1 November 2014 and 1 November, 2015. If he retires on 1 January, 2016, what pension does he draw approximately?
A. 4436
B. 2216
C. 2417
D. 3227
Solutions
Form 1 January 2013 to 1 November 2013= 10 x 4600 = 46000
From 1 November 2013 to 1 November 2014 = 12 x 4800=57600
From 1 November 2014 to 1 November 2015 = 12 x 5000=60000
From 1 November 2015 to 1 Jan 2016 = 2 x 5200 =10400
Average of 36 month = (46000+60000+57600+10400)/36 = 4833.33
So pension per month = 4833.33/2 = 2416. 66 = 2417
4. The circumference of the front wheel of a cart is 35 cm long and that of the back wheel is 40 cm long. What is the distance travelled by the cart, when the front wheel has done five more revolutions than the rear wheel?
A. 12.5 m
B. 25 m
C. 16 m
D. 14 m
Solutions
The circumference of the front wheel is 40 cm and that of the rear wheel is 30 cm.
Let the rear wheel make n revolutions. At this time, the front wheel should have made n+5 revolutions.
As both the wheels would have covered the same distance, n x 40 = (n+5) x 35
40n = 35n + 5 x 35
5n = 5 x 35
N = 35
Distance travelled = 35 x 40 =1400 cm =14 m
5. Assuming that m is a positive real number x, y, z is rational numbers. Find the value of following

6. A shopkeeper calculated his intended selling price at 7.2% profit on the cost of a product. However while selling; the unit digit and tens’ digit of the selling price got interchanged by mistake. By the way the profit by Rs. 90 and profit percentage to 3.6%. What is the cost price of the product?
A. 5000 Rs
B. 2500 Rs
C. 8000 Rs
D. 4000 Rs
Solutions
Profit % reduced by = 7.2 – 3.6 = 3.6 %
3.6 % CP = 90
3.6/100 CP = 90
CP = 90000/36 = 2500
7. If the ages of Priti and Riya are added to twice the age of Isha, the total becomes 59. If the ages of Isha and Riya are added to thrice the age of Priti, the total becomes 68 and if the age of Priti is added to thrice the age of Isha and thrice the age of Riya, the total becomes 108. What is the age of Priti ?
A. 17 year
B. 19 year
C. 12 year
D. 15 year
Solutions
Priti + Riya + 2 Isha = 59 —-(1)
3 Priti +Riya+ Isha =68 ——(2)
Priti + 3 Riya + 3 Isha = 108 —–(3)
Multiply eq. (2) by 3 and subtract eq (3) from it
(×3) 3 Priti +Riya+ Isha = 68
9 Priti + 3 Riya + 3 Isha = 204
Priti + 3 Riya + 3 Isha = 108
8 Priti = 96
Priti = 12 years
8. If 30 women and 14 children can finish a work in 21 days, in how many days will 20 women and 4 children can finish it, supposing that 3 women can do as much as 5 children?
A. 30 days
B. 32 days
C. 36 days
D. 35 days
Solutions
3 women = 5 children
W= 5/3 C
50 c + 14 c = 21 days
64 children 1 day work = 1/21
1 children 1 day work = 1/ (21 x 64)
20 w + 4 c=100/3 c + 4c = 112 / 3 c
So 20 w + 4 c →1 day work = 112/ 3 x 1/ (21 x 64)
= 112/ (21 x 64 x 3) = 1/36
(20 w + 4 c) can finish the work in 36 days.

37 + 441/ 8 =?3 + 28.125
37 + 55.125 – 28.125 =?3
?3 = 64
? = 4
