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.

Let, Boys = 100

Girls = 200

200 × 30% + 100 × 45%

= 60 + 45

= 105

300 - 105 /300 × 100%

= 195 / 300 × 100%

= 65%

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.

x = 144

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

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

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.

z = 45y
Average of all 3 = (83x + 76y + 85z)/(x + y + z)
=81.5
