Written Math Solution:
7.
A. A basin can be filled by tape A in 5 hrs and tape B by 8 hours, each tape working in its own. When the basin is full a drainage hole is open.the water is drain in 20 hours. If initially the basin is empty and someone started the two tape together but the left the drainage hole is open how long does it take for the basin to be filled?
Ans: 40/11 hours/3 hr 37 min
Full Solution:
In an hr,
A fills 1/5 part
B fills 1/8 part
Hole drains 1/20 part
So, in an hr basin becomes filled by
=(1/5 + 1/8 – 1/20) part
=11/40 part
So, time needed =40/11 hr
= 3 hr 37 min
B. A circular garden surrounded by a road. if the outer circumference is greater than the inner circumference by 88 m what is the width of the road?
Ans: 14 m
Full Solution:
Let, the width of the path be x meter
And radius be r meter
Circumference with path=2π(r+x)
Circumference without path=2πr
ATQ,
2π(r+x) – 2πr = 88
Or, 2π(r+x-r)=88
Or, x=88/2π [π=22/7]
Or, x=14
Thus, width of the path is 14 meter
C. A microbus was hired at Tk 5500 to travel intercity. The fare is shared equally among the passengers on they day of travel, but due to absence of 5 passengers, the average fare of per person was doubled. How many people avail the service.
Ans: 5
Full Solution:
Let, Initial passenger= x
Fare = 5500/x
Case 2:
If passengers = (x-5)
Fare = 5500/(x-5)
ATQ,
2*5500/x= 5500/(x-5)
=> 2x-10= x
=> x= 10
People avail the service = (10-5)= 5 persons
D. If (a-1/a)=3, prove that (a⁴+1/a⁴)=119
Ans: Proved
Full Solution:
Given that, a + 1/a = 3
To be proved, a^4 + 1/a^4 = 119
LHS=a^4 + 1/a^4
=(a^2)^2 + 1/(a^2)^2
=(a^2 + 1/a^2)^2 – 2*a^2*1/a^2
={(a)^2 + (1/a)^2}^2 – 2
={(a – 1/a)^2 + 2*a*1/a}^2 – 2
={(3)^2 + 2}^2 – 2
=(11)^2 – 2
=119
RHS=119
So, LHS=RHS (Proved)
E. The sum of the ages of a mother and daughter is 60 years. Also, 5 years ago, the mother’s age was 4 times the age of the daughter. The ratio of their ages after 10 years?
Ans: 11:5
Full Solution:
Let, present age of
Mother=x
Daugther=60-x
ATQ,
(x-5) : (60-x-5) = 4:1
Or, (x-5)/(55-x)=4/1
Or, x-5 = 220-4x
Or, 5x=225
Or, x=45
Mother=45
Daughter=60-45=15
Ratio after 10 years,
Mother:Daughter=(45+10):(15+10)
=55:25
=11:5
F. In boys’ school, if 5 students sit in every bench, 4 bench are empty. But if 3 students sit in every bench, 20 students are left standing. What’s the number of benches in the class?
Ans: 20 bench
Full Solution:
Let, number of benches be x
ATQ,
5*(x-4) = 3x + 20
Or,5x-3x=20+20
Or, x=20
So, the number of benches is 20
G. The sum of three times the smaller and four times the larger is 71. And twice the larger of two numbers is three more than five times the smaller. What’re the numbers?
Ans: 14 & 5 respectively
Full Solution:
Let, smaller one be x
And larger one be y
ATQ,
3x+4y=71….. (i)
2y=5x+3……..(ii)
From (i)
y=(5x+3)/2…(iii)
Putting the value of y in (i)
3x + 4*(5x+3)/2 = 71
Or, 3x + 10x + 6 = 71
Or, x=5
Putting the value of x in (iii)
y=(5*5 + 3)/2
=14
So, smaller one is 5 and larger one is 14

Written Math Answer:
1. On a river , Q is the mid – point between two points P and R on the same bank of the river. A boat can go from P to Q and back in 12 hours, and from P to R in 16 hours 40 minutes. How long would it take to go from R to P?
Ans: 7.33 hours/ 7 hours 20 Minutes
Full Solution:
Time taken,
P to R = 16 hrs 40 min
So, P to Q = 8 hrs 20 min
P to Q + Q to P= 12 hrs
P to Q =8 hrs 20 min
So, Q to P= 3 hrs 40 min
Thus, R to P = 2*(3 hrs 40 min)
=7 hrs 20 min
2. A mixture contain two liquid in the ratio of 2:3. And another mixture contain the same two liquid in the ratio of 5:4. Find the ratio in which the contents of both the vessels must be mixed to get a new mixture containing two liquid in the ratio equally?
Ans: 5:9
Full solution:
Ratio from 1st mixture=2X,3X
Ratio from 2nd mixture=5Y,4Y
ATQ,
2X/5 +5Y/9 =3X/5 +4Y/9
=> 2X/5 -3X/5 =4Y/9 -5Y/9
=> X/5 =Y/9
=> X:Y=5:9
Ans: 5:9
3. A train 108 m long moving at a speed of 50 km/hr crosses a train 112 m long coming from opposite direction in 6 seconds.The speed of the second train is?
Ans: 82 km/hr
Full Solution:
Let, the speed of 2nd train= x km/hr
ATQ,
6*(50+x)*5/18=108+112
Or, 50+x=132
Or, x=82
So, the speed of 2nd train is 82 km/hr
4. A & B together can do a piece of work in 30 days. A having worked for 16 days, B finishes the remaining work alone in 44 days. In how many days shall B finish the whole work alone?
Ans: 60 days
Full Solution:
Let, B can do the work in x days.
In a day, B does = 1/x part
So, A does = 1/30 – 1/x =(x-30)/30x part
ATQ,
16*(x-30)/30x + 44/x = 1
Or,16x-480+1320=30x
Or, 14x=840
Or, x=60
So, B needs 60 days to complete the work alone.
5. A box contains 3 blue marbles, 4 red, 6 green marbles and 2 yellow marbles. If two marbles are drawn at random, what is the probability that at least one is green?
Full solution:
Given,
Red= 4
Blue=3
Green=6
Yellow=2
[At least one green that means highest green=2 we can take]
P=(6C1×3C1)/15C2 +(6C1×4C1)/15C2+(6C1×2C1)/15C2 +6C2/15C2
=(6×3)/15C2 +(6×4)/15C2 +(6×2)/15C2 +6/15C2
=(18+24+12+15)/15C2
=69/(15×14/2)
=69/105
=23/35
Ans: 23/35
6. If x + 2/x= 1, then evaluate the value of (x^2+x+2)/x^2(1-x)
Ans: 1
Full Solution:
Given,
x + 2/x = 1
Or, x^2 + 2 = x
Or, 2 = x-x^2
Or, 2 = x(1-x)
Or, 1-x = 2/x
The value of (x^2 + x + 2) / x^2(1 – x)
=(x^2 + 2 + x) / x^2(1 – x)
=(x+x)/(x^2 * 2/x)
=2x/2x
=1
7. In a three digit number unit digit is double of tenth digit and 1.5 times of hundred digit. Sum of three digit is 13. Find the number
Ans: 436
Full Solution:
Let, unit digit=x
10th digit=x/2
100th digit=x/1.5=2x/3
ATQ,
x + x/2 + 2x/3 = 13
Or, 6x+3x+4x=78
Or, x=6
Unit digit=6
10th digit=3
100th digit=4
So, Number=436
