D. 54 days

View Answer	Favorite Question

Answer: Option D

Explanation:

Work equivalence method:
1200 × 45 = 1000 × x
Hence, x = 54 days
Variation Method:
After 15 days 200 soldiers left.
Soldiers Food for days
1200 ↓ 45
1000 ↑ x (let)
Arrows show the opposite variation to each other
1200/1000 = x/45
Or, x = (1200 × 45)/1000
= 54 days.

Explanation:

Let, Boys = 100

Girls = 200

200 × 30% + 100 × 45%

= 60 + 45

= 105

300 - 105 /300 × 100%

= 195 / 300 × 100%

= 65%

So, Smaller ratio 1 = 9/3 = 3

Now,

Highest ratio 19 = 19×3 = 57

3262 . Three boys have marbles in the ratio of 19: 5: 3 If the boy with the least number has 9 marbles, how many marbles does the boy with the greatest number have?

A. 57
B. 33
C. 27
D. 81

View Answer	Favorite Question

Answer: Option A

Explanation:

Let's call the number of marbles each boy has as follows:

Boy A has 19x marbles. Boy B has 5x marbles. Boy C has 3x marbles.

We are given that Boy C has the least number of marbles, which is 9. So, we can set up the equation:

3x = 9

Now, let's solve for x:

3x = 9 x = 9 / 3 x = 3

Now that we know the value of x, we can find the number of marbles Boy A has:

Boy A has 19x = 19 * 3 = 57 marbles.

So, the boy with the greatest number of marbles is Boy A, and he has 57 marbles.

Answer: Option A

Explanation:

Let the capacity of each truck and the reservoir be T and R respectively.

Total capacity of five trucks = 5T

According to the question, 5T = 3/4 of R

or, T = 3/4 x R / 5 = (3/20) R

So, each truck received 3/20 of the reservoir.

3268 . Three individuals contributed Tk.8000 each toward the purchase of a computer. If they bought the computer on sale for Tk.19500 plus 10% sales tax, how much money should be refunded to each individual?

A. Tk.1500
B. Tk.1950
C. Tk.650
D. Tk.850

View Answer	Favorite Question

Answer: Option D

Explanation:

Total contribution = 3 x 8000 = 24000 TK

Cost of computer = 19500 + 10% of 19500 = 19500 + 1950 = 21450 TK.

Excess contribution = 24000 - 21450 = 2550 TK.

Refund to each = 2550/3 = 850 TK.
