## Written Maths Solution:

1. A sum of taka 725 is lent in the beginning of a year at a certain rate of interest. After 8 months, a sum of tk 362.50 more is lent but at the rate of twice the former. At the end of the year Tk 33.50 is earned as interest from both the loans. what was the original rate of Interest ?

**Ans:** 3.46% (Approximately)

**Detail Full Solution:**

Let, Initial Rate = r%

Final rate = 2r%

ATQ,

725*1* r/100+ (362.5)*(1/3)*2r/100= 33.50

=> 725r+ 241.67r= 3350

=> r= 3.46%

2. If x+1/x=2; find the value of x^17+1/(x^19)=?

**Ans:** 2

**Detail Full Solution:**

x+ 1/x = 2

=> x^2+1= 2x

=> x^2-2x+1= 0

=> x^2-x-x+1= 0

=> x(x-1)-1(x-1)= 0

=> x= 1

**Now,**

x^17+ 1/x^19

= (1)^17+1/(1)^19

= 1+1

= 2

3. Two men X and Y started working for a certain company at similar jobs on January 1, 1950. X asked for an initial salary of Rs. 300 with an annual increment of Rs. 30. Y asked for an initial salary of Rs. 200 with a rise of Rs. 15 every six months. Assume that the arrangements remained unaltered till December 31, 1959. Salary is paid on the last day of the month. What is the total amount paid to them as salary during the period?

**Ans:** 93,300

**Detail Full Solution:**

X salary for first year = 12*300= 3600 for first year

Salary up to 1959 = (3600+3960+———–+n)

Here, n= 10

a = 3600

d= 360

Total salary = 10/2*{2*3600+(10-1)*360}

= 5{7200+9*360}= 52,200

Y salary up to 1959

= 1200 for 6 month

= 1200+ 15*6= 1290 for next six month

Total salary of Y = 20/2*{2*1200+19*90}

= 41,100

Total Salary = (52,200+41,100)

= 93,300

4. In a flight of 600 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced by 200 km/hr and the time of flight increased by 30 minutes. The duration of the flight is?

**Ans:** 1 Hour

**Detail Full Solution:**

Let the duration of the flight be x hours.

x(2x + 1) = 3

2×2 + x – 3 = 0

(2x + 3)(x – 1) = 0

x = 1 hr. [neglecting the -ve value of x]

or,

Flight Distance= 600 km

Let, Avg. Time = t

New time = (t+1/2) hr

ATQ,

600/t – 600/(t+1/2)= 200

=> 600/t – 600/(2t+1)/2= 200

=> 600/t -1200/(2t+1)= 200

=> (1200t+600-1200t)= 200*t(2t+1)

=> 600= 200(2t^2+t)

=> 600= 400t^2+200t

=> 400t^2+200t-600= 0

=>4t^2+2t-6= 0

=> 2t^2+t-3= 0

=> 2t^2+3t-2t-3= 0

=> t(2t+3)-1(2t+3)= 0

So, t= 1hr

5. Three pipes A, B and C can fill a tank in 6 hours. After working at it together for 2 hours, C is closed and A and B can fill the remaining part in 7 hours. How many hours will take C alone to fill the tank ?

=> 12P= 10Q

=> P:Q= 5:6

ATQ,

96*5= 8*(5+6)*D

=> 60= 11 D

=> D= 60/11
