B. Tk. 160
C. Tk. 180
D. Tk. 220

663 . A,B and C enter into partnership. A invests some money at the beginning, B invest double the amount after 6 months and C invests thrice the amount after 8 months. If the annual profit be Tk. 27,000, C's share is:

A. Tk. 11,250
B. Tk. 8,625
C. Tk. 9,000
D. Tk. 10,800

View Answer	Favorite Question

Answer: Option C

Explanation:

To find C's share of the annual profit, we'll first calculate the individual contributions of A, B, and C based on their investment durations.

Let's assume A's initial investment is "x" Tk. Since B invests double the amount after 6 months, B's investment at the beginning was "2x" Tk, and C invests thrice the amount after 8 months, so C's investment at the beginning was "3x" Tk.

Now, we need to consider the time each partner's money is invested:

A's money is invested for 12 months (the whole year).
B's money is invested for 6 months (half a year).
C's money is invested for 4 months (12 months - 8 months).
Now, let's calculate their shares of the profit based on their investments:

A's share = (A's investment duration / Total investment duration) * Total profit A's share = (12 / 12) * 27,000 = 27,000 Tk

B's share = (B's investment duration / Total investment duration) * Total profit B's share = (6 / 12) * 27,000 = 13,500 Tk

C's share = (C's investment duration / Total investment duration) * Total profit C's share = (4 / 12) * 27,000 = 9,000 Tk

So, C's share of the annual profit is Tk. 9,000.

664 . A 10% monthly salary increase resulted in a TK. 9000 per year increase in salary for an employee. What was his monthly salary before the increase?

A. Tk. 5000
B. Tk. 9000
C. TK. 7500
D. TK. 12000

View Answer	Favorite Question

Answer: Option C

Explanation:

Yearly increase = 9000 tk

Monthly increase = 9000/12 = 750 tk

10% of Salary is = 750 tk

100% of Salary is = (750×100)/10 = 7500 tk .

669 . A 40-meter long rope is cut into two unequal pieces. If one piece is 18 meter longer than the other, what is the length ( in meter ) of the shorter piece ?

A. 10
B. 11
C. 18
D. None of these

View Answer	Favorite Question

Answer: Option B

Explanation:

Let,

shorter length = X

∴ Bigger length = X + 18

ATQ,

X + (X + 18) = 40

2x + 18 = 40

2x = 40 - 18

2x = 22

∴ x = 11

671 . A 45,000 liter water tank is to filled at the rate 220 liters per minute. Estimates to the nearest half hour, how long it will take to fill the tank?

A. 4 hours
B. 3.5 hours
C. 3 hours
D. 2.5 hours

View Answer	Favorite Question

Answer: Option B

Explanation:

Assume that the tank fills in x minutes

By Direct Proportion,

x1/y1 = x2/y2

220/1 = 45000/x

x = 45000/220

x = 204.54

x = 205 minutes (approx.)

Divide x by 60 in order to convert from Minutes to Hours

⇒ 205/60 = 3.41 hours

Estimating to nearest half hours,

The 45000 L tank is filled in 3.5 hours at the rate of 220 L/m

A. 1.25
B. 1.5
C. 2
D. 2.25

View Answer	Favorite Question

Answer: Option C

Explanation:

Let the longer segment be m.

Therefore, the shorter segment is (2/3)m = 2m/3

Now, m + 2m/3 = 5 or, m = 3

Therefore, the shorter segment is (2/3) x 3 = 2 meter.

675 . A 70cm long wire is to be cut into two pieces such that one piece will be 2/5 as long as the other. How many centimetres will the shorter piece be ?

A. 10
B. 14
C. 20
D. 28

View Answer	Favorite Question

Answer: Option C

Explanation:

Hints: Let the other price be of length x cm, so the shorter price = 2/5 of x = 2x / 5

Now, 2/5 x + x = 70

7/5 x = 70

x = 50 and 2/5 x = 2/5 × 50 = 20 cm
