A. Tk. 166
B. Tk. 320
C. Tk. 400
D. Tk. 720
E. None of these

View Answer	Favorite Question

Answer: Option B

Explanation:

Let the investments be A and (7200 - A) respectively.

Interest, I = P n r

Now, A × 1 × 4/100 = (7200 - A) × 1 × 5/100

or, 4A = 5×7200 - 5A

or, 5A + 4A = 36000

or, 9A = 36000

or, A = 4000

So, total income = A × 1 × 4/100 + (7200 - A) × 1 × 5/100

= 4000×4/100 + (7200 - 4000)×5/100 = 160 + 160 = 320 TK

1056 . A portion of the 7200 is invested at 4% annual return, while the remainder is invested at a 5% annual return. If the annual income from both portion is the same, what is the total income from the two investments?

Answer: Option C

Explanation:

Service charge for the 1st order = 75 tk (As the amount is less than Tk.2500)

Service charge for the 2nd order = 75 tk (As the amount is equal to TK.2500)

Service charge for the 3rd order = 100 tk (As the amount is more than Tk.2500)

Therefore, the total service charge = 75 + 75 + 100 = 250 tk

ans: 250 tk

1059 . A predator is chasing its prey. The predator takes 4 leaps for every 6 leaps of the prey and the predator covers as much distance in 2 leaps as 3 leaps of the prey. Will the predator succeed in getting its food ?

A. Yes
B. In the 6th leap
C. Never
D. Can't be determined
E. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

If predator takes 2 leaps and prey takes 3 leaps to cover the same distance, then multiplying the distance by 2 you get predator 4 leaps and prey 6 leaps. With this ratio, they are covering the same distance with their respective leaps.

Therefore, they will always be the same distance away from each other unless either changes its speed.

so, ans: can't be determined.

A. 78
B. 132
C. 204
D. 216

View Answer	Favorite Question

Answer: Option C

Explanation:

best des
Area of the rectangle without the road = 16×12 = 192 sq. m.

Length with road on both side = 16 + 2×3 = 22 m.

Width with road on both side = 12 + 2×3 = 18 m.

Area of the rectangle including the road = 22×18 = 396 sq. m.

Area of the road = 396 - 192 = 204 sq. m.

1064 . A rectangle is 14 cm long and 10 cm wide. If the length is reduced by x cms and its width is increased also x cms so as to make it a square, then its area changes by:

A. 4
B. 144
C. 12
D. 2

View Answer	Favorite Question

Answer: Option A

Explanation:

Let's call the new length of the rectangle "L" after reducing the length by x cm and increasing the width by x cm. Then, the new width of the rectangle would be "W".

We know that the original length of the rectangle was 14 cm and the original width was 10 cm, so we can write the following equations:

L = 14 - x
W = 10 + x

To make the rectangle into a square, the length and the width must be equal, so we can set L = W:

14 - x = 10 + x
24 = 20
x = 2

Now that we know x = 2, we can use that to find the new length and width of the rectangle:

L = 14 - 2 = 12
W = 10 + 2 = 12

The area of the original rectangle was 14 cm * 10 cm = 140 sq cm. The area of the new square is 12 cm * 12 cm = 144 sq cm. The difference between the two is 144 - 140 = 4 sq cm.

So, the area changes by 4 sq cm when the rectangle is transformed into a square.

1065 . A rectangle is 14 cm long and 10 cm wide . If the length is reduced by x cms and its width is increased also by x cms so as to make it a square, then its area changes by :

A. 4
B. 144
C. 12
D. 2
E. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

Area = 14 × 10 = 140 sq.cm

New length = ( 14 - x)

New width = ( 10 + x)

14 - x = 10 + x

2x = 4

x = 2

New Area = ( 14 - 2) × ( 10 + 2) = 144

change is area = ( 144 - 140) sq.cm = 4 sq.cm
